At this year's meeting, you will be asked to consider and to vote upon the election of three directors. Your Board of Directors unanimously recommends that you vote FOR the nominees.

You will also be asked to ratify the appointment of KPMG LLP as our independent registered public accounting firm for the 2006 fiscal year. The Board continues to be satisfied with the services KPMG LLP has rendered to Minerals Technologies Inc., and unanimously recommends that you vote FOR this proposal.

The two items upon which you will be asked to vote are discussed more fully in the Proxy Statement. I urge you to read the Proxy Statement completely and carefully so that you can vote your interests on an informed basis.

Your vote is important. Whether or not you plan to attend the meeting, and regardless of the number of shares you own, your representation and vote are very important and you should vote your shares. Therefore, I urge you to complete, sign, date and return the enclosed proxy card promptly in the accompanying postage prepaid envelope. All stockholders of record, and many street-name holders, may also vote by internet, or by touchtone telephone from the United States and Canada, using the instructions on the proxy card. If you return a signed proxy without marking it, it will be voted in accordance with management's recommendations. You may, of course, attend the Annual Meeting and vote in person, even if you have previously submitted a proxy.

		Sincerely,

		Paul R. Saueracker Chairman, President and Chief Executive Officer

PROXY STATEMENT

This proxy statement (“Proxy Statement”) contains information related to the annual meeting of stockholders (the “Annual Meeting”) of Minerals Technologies Inc. (the “Company”) to be held at 2:00 p.m. on Wednesday, May 24, 2006, at 1 Highland Avenue, Bethlehem, Pennsylvania 18017. Minerals Technologies Inc. is sending this Proxy Statement and form of proxy to its stockholders on or about April 4, 2006.

QUESTIONS AND ANSWERS ABOUT THE PROXY MATERIALS
AND THE ANNUAL MEETING

Why am I being sent these materials?

Ø		Minerals Technologies Inc. is sending this Proxy Statement and form of proxy card to its stockholders to ask them to appoint proxies who will represent them at the Annual Meeting of Stockholders. If a quorum does not attend or is not represented by proxy, the meeting will have to be adjourned and rescheduled.

Who is asking for my proxy?

Ø		The Board of Directors asks you to submit a proxy for your shares so that even if you do not attend the meeting, your shares will be counted as present at the meeting and voted as you direct.

What is the agenda for the Annual Meeting?

Ø		At the Annual Meeting, stockholders will vote on two questions: the election of Dr. Kristina M. Johnson, Mr. Michael F. Pasquale and Dr. John T. Reid as members of the Board of Directors, and ratification of the appointment of KPMG LLP as our independent registered public accounting firm. Also, our management will make a brief presentation about the business of Minerals Technologies Inc., and representatives of KPMG LLP will make themselves available to respond to any questions from the floor.

		The Board does not know of any other business that will be presented at the Annual Meeting. The form of proxy gives the proxies discretionary authority with respect to any other matters that come before the Annual Meeting, and if such matters arise the individuals named in the proxy will vote according to their best judgment.

How does the Board of Directors recommend I vote?

Ø		The Board unanimously recommends that you vote for each of the nominees for director, Kristina M. Johnson, Michael F. Pasquale and John T. Reid, and for ratification of the appointment of KPMG LLP to continue as our auditors.

Who can attend the Annual Meeting?

Ø		Any stockholder of Minerals Technologies Inc., employees, and other invitees may attend the Annual Meeting.

Who can vote at the Annual Meeting?

Ø		Anyone who owned shares of our Common Stock at the close of business on March 27, 2006, the “Record Date,” may vote those shares at the Annual Meeting. Each share is entitled to one vote.

What constitutes a quorum for the meeting?

Ø		According to the by-laws of Minerals Technologies Inc., a quorum for all meetings of stockholders consists of the holders of a majority of the shares of common stock issued and outstanding and entitled to vote, present in person or by proxy. On the Record Date there were 19,882,940 shares of common stock issued and outstanding, so at least 9,941,471 shares must be represented at the meeting for business to be conducted.

		Shares of common stock represented by a properly signed and returned proxy are treated as present at the Annual Meeting for purposes of determining a quorum, whether the proxy is marked as casting a vote or abstaining.

		Shares represented by “broker non-votes” are also treated as present for purposes of determining a quorum. Broker non-votes are shares held in record name by brokers or nominees, as to which the broker or nominee (i) has not received instructions from the beneficial owner or person entitled to vote, (ii) does not have discretionary voting power under applicable New York Stock Exchange rules or the document under which it serves as broker or nominee, and (iii) has indicated on the proxy card, or otherwise notified us, that it does not have authority to vote the shares on the matter.

		If a quorum does not attend or is not represented, the Annual Meeting will have to be postponed.

How many votes are required for each question to pass?

Ø		The by-laws state that directors are to be elected by a plurality vote of the shares of stock present and entitled to vote, in person or by proxy. All other questions are determined by a majority of the votes cast on the question, except as otherwise provided by law or by the Certificate of Incorporation of Minerals Technologies Inc.

What is the effect of abstentions and broker non-votes?

Ø		Abstentions and broker non-votes as to the election of directors will not affect the outcome of the election of directors. All other questions require a majority of votes cast in order to pass. All votes cast in favor of a given proposal, and all votes cast against it, are added together for a total sum of votes on that proposal. Abstentions and broker non-votes as to the proposal will not affect the outcome, because they will not be included in calculating the number of votes necessary for approval and will not count as votes cast for or against the question.

Who will count the votes?

Ø		A representative of our transfer agent, Computershare Trust Company, N.A., will serve as inspector of election.

Who are Minerals Technologies Inc.’s largest stockholders?

Ø		As of February 3, 2006, American Century Companies, Inc. owned 10.9%; Primecap Management Company owned 10.2%; Manning & Napier Advisors, Inc. owned 8.1%, Vanguard Horizon Funds—Vanguard Capital Opportunity Fund owned 7.8%, FMR Corp. owned 7.3%; Dimensional Fund Advisors Inc. owned 5.4% and State Street Bank and Trust Company owned 5.1% of our common stock. No other person owned of record, or, to our knowledge, owned beneficially, more than 5% of our common stock.

How can I cast my vote?

Ø		You can vote by completing and mailing the enclosed proxy. We ask you to mark your choices, sign, date and return the proxy as soon as possible in the enclosed postage prepaid envelope.

		All stockholders of record, and many street-name holders, can also vote by internet, or by touchtone telephone from the United States and Canada, using the instructions on the proxy card.

		You can attend the Annual Meeting and vote your shares in person; if you do, you should bring the enclosed proxy card with you as proof of the number of shares you owned on the Record Date.

What if I submit a proxy but don’t mark it to show my preferences?

Ø		If you return a properly signed proxy without marking it, it will be voted in accordance with management’s recommendations on all proposals.

What if I submit a proxy and then change my mind?

Ø		If you submit a proxy, you can revoke it at any time before it is voted by submitting a written revocation or a new proxy, or by voting in person at the Annual Meeting. However, if you have shares held through a brokerage firm, bank or other custodian, you can revoke an earlier proxy only by following the custodian’s procedures.

Who is paying for this solicitation of proxies?

Ø		Minerals Technologies Inc. pays the cost of this solicitation. In addition to soliciting proxies through the mail using this Proxy Statement, we may solicit proxies by telephone, facsimile, electronic mail and personal contact. These solicitations will be made by our regular employees without additional compensation. We have also engaged Morrow & Co., Inc. to assist in this solicitation of proxies, and we have agreed to pay that firm $4,000 for its assistance, plus expenses.

Where can I learn the outcome of the vote?

Ø		The Corporate Secretary will announce the preliminary voting results at the Annual Meeting, and we will publish the final results in our quarterly report on Form 10-Q for the second quarter of 2006.

CORPORATE GOVERNANCE

The Board of Directors has established Corporate Governance Guidelines pursuant to which all members of the Board of Directors are expected to attend the Annual Meeting of Stockholders. The Board has established a code of ethics for the Company’s chief executive officer, chief financial officer, and chief accounting officer, entitled Code of Ethics for Senior Financial Officers. The Board has also established a code of business conduct and ethics for directors, officers and employees of the Company entitled Summary of Policies on Business Conduct. The Corporate Governance Guidelines, the Code of Ethics for Senior Financial Officers and the Summary of Policies on Business Conduct are posted on our website, www.mineralstech.com, under the link entitled “Corporate Governance” and are available in print to any stockholder who requests them by writing to Secretary, Minerals Technologies Inc., The Chrysler Building, 405 Lexington Avenue, New York, New York 10174-0002.

The Board of Directors met seven times in 2005. Each of the directors attended at least 75% of the meetings of the Board and committees on which he or she served in 2005. At each regular meeting of the Board of Directors, the independent directors meet in executive session outside the presence of the non-independent directors or any member of management. These executive sessions are presided over by the chair of the committee that has primary responsibility for the principal matter to be discussed. If no specific topic is proposed for the executive session, then the position of presiding director rotates among the chairs of the Audit, Compensation, and Corporate Governance and Nominating committees.

The Board has adopted the following categorical standards to guide it in determining whether a member of the Board can be considered “independent” for purposes of Section 303A of the Listed Company Manual of the New York Stock Exchange: A director will not be independent if, within the preceding three years:

Ø		the director was employed by the Company, or an immediate family member of the director was employed by the Company, as an executive officer;
Ø		the director or an immediate family member of the director received more than $100,000 per year in direct compensation from the Company, other than director and committee fees and pensions or other forms of direct compensation for prior service (provided such compensation is not contingent in any way on continued service);
Ø		the director was employed by or affiliated with the Company’s independent registered public accounting firm or an immediate family member of the director was employed by or affiliated with the Company’s independent registered public accounting firm in a professional capacity;
Ø		the director or an immediate family member was employed as an executive officer of another company where any of this Company’s present executives served on that company’s compensation committee; and
Ø		the director was an executive officer or an employee, or had an immediate family member who was an executive officer, of a company that made payments to, or received payments from, the Company for goods or services in an amount which, in any single fiscal year, exceeded the greater of $1,000,000 or 2% of the other company’s consolidated gross revenues.

In the case of each director who qualifies as independent, the Board is aware of no relationships between the director and the Company and its senior management, other than the director’s membership on the Board of the Company and on committees of the Board. As a result of its application of the categorical standards and the absence of other relationships, the Board has affirmatively determined (with each member abstaining from consideration of his or her own independence) that none of the non-employee members of the Board violates the categorical standards or otherwise has a relationship with the Company and, therefore, each is independent. Specifically, the Board has affirmatively determined that Ms. Paula H. J. Cholmondeley, Mr. John B. Curcio, Mr. Duane R. Dunham, Mr. Steven J. Golub, Dr. Kristina M. Johnson, Mr. Joseph C. Muscari, Mr. Michael F. Pasquale, Dr. John T. Reid, Mr. William C. Stivers and Dr. Jean-Paul Vallès, comprising all of the non-employee directors, are independent.

Stockholder Proposals

The following are Minerals Technologies Inc.’s procedures for considering stockholder nominations for election to the Board of Directors, as well as other items of business. While the Board has not established any minimum set of qualifications for membership on the Board, it is expected that candidates will have substantial business experience, some familiarity with the industries that Minerals Technologies Inc. serves, and an understanding and appreciation of the responsibilities of a company whose shares are listed on a national securities exchange.

The Corporate Governance and Nominating Committee will consider nominations of candidates for director, and the Board of Directors will consider other items of business, that are proposed by stockholders. The Company’s by-laws describe the procedures that a stockholder must follow to nominate a candidate for director or to introduce an item of business at a meeting of stockholders. These procedures provide that nominations for directors and items of business to be introduced at an annual meeting of stockholders must be submitted in writing to the Corporate Secretary of Minerals Technologies Inc. at The Chrysler Building, 405 Lexington Avenue, New York, NY 10174-0002. If intended to be considered at an annual meeting, the nomination or proposed item of business must be received not less than 70 days nor more than 90 days in advance of the first anniversary of the previous year’s annual meeting. Therefore, for purposes of the 2007 annual meeting, any nomination or proposal must be received between February 23 and March 15, 2007. With respect to any other meeting of stockholders, the nomination or item of business must be received not later than the close of business on the tenth day following the date of our public announcement of the date of the meeting. Under the rules of the Securities and Exchange Commission, if a stockholder proposal intended to be presented at the 2007 annual meeting is to be included in the proxy statement and form of proxy relating to that meeting, we must receive the proposal at the address above no later than 120 days before the anniversary of the mailing date of the Company's proxy statement in connection with the 2006 annual meeting. Therefore, for purposes of the 2007 annual meeting, any such proposal must be received by no later than December 5, 2006.

The nomination or item of business must contain:

Ø		The name and address of the stockholder giving notice, as they appear in our books (and of the beneficial owner, if other than the stockholder, on whose behalf the proposal is made);
Ø		The class and number of shares of stock owned of record or beneficially by the stockholder giving notice (and by the beneficial owner, if other than the stockholder, on whose behalf the proposal is made);
Ø		A representation that the stockholder is a holder of record of stock entitled to vote at the meeting, and intends to appear at the meeting in person or by proxy to make the proposal; and
Ø		A representation whether the stockholder (or beneficial owner, if any) intends, or is part of a group which intends, to deliver a proxy statement and form of proxy to holders of at least the percentage of outstanding stock required to elect the nominee or approve the proposal and/or otherwise solicit proxies from stockholders in support of the nomination or proposal.

Any notice regarding the introduction of an item of business at a meeting of stockholders must also include:

Ø		A brief description of the business desired to be brought before the meeting;
Ø		The reason for conducting the business at the meeting;
Ø		Any material interest in the item of business of the stockholder giving notice (and of the beneficial owner, if other than the stockholder, on whose behalf the proposal is made); and
Ø		If the business includes a proposal to amend the by-laws, the language of the proposed amendment.

		Any nomination of a candidate for director must also include:

Ø		A signed consent of the nominee to serve as a director, if elected;
Ø		The name, age, business address, residential address and principal occupation or employment of the nominee;
Ø		The number of shares of Minerals Technologies Inc. common stock beneficially owned by the nominee; and
Ø		Any additional information that would be required under the rules of the Securities and Exchange Commission in a proxy statement soliciting proxies for the election of that nominee as a director.

Stockholders and any other interested parties may communicate by e-mail with the independent members of the Board at the following address: independent.directors@mineralstech.com. The independent members of the Board have direct access to all messages sent to this address; the messages are monitored by the office of the General Counsel of Minerals Technologies Inc. No message sent to this address will be deleted without the approval of the chair of whichever committee of the Board has primary responsibility for the principal subject matter of the message.

COMMITTEES OF THE BOARD OF DIRECTORS

The Board of Directors has established, and approved formal written charters for, an Audit Committee, a Compensation Committee, and a Corporate Governance and Nominating Committee. The full texts of the charters of these three committees are available at our website, www.mineralstech.com, by clicking on “Corporate Governance” and are available in print to any stockholder who requests them by writing to Minerals Technologies Inc., The Chrysler Building, 405 Lexington Avenue, New York NY 10174-0002, Attn: Corporate Secretary.

The Audit Committee

The Audit Committee consists of Mr. Stivers (Chair), Ms. Cholmondeley, Dr. Johnson, Mr. Pasquale and Dr. Reid, who are not employees of Minerals Technologies Inc. The Board of Directors has determined that each member of the Audit Committee is independent and financially literate in accordance with the rules of the New York Stock Exchange, as well as being independent under the rules of the Securities and Exchange Commission. The Board has also determined that each of Mr. Stivers, Chair of the Audit Committee, and Mr. Pasquale, is an “audit committee financial expert” for purposes of Section 407 of the Sarbanes-Oxley Act of 2002, and has “financial expertise” for purposes of the rules of the New York Stock Exchange.

Ms. Cholmondeley serves as a member of the audit committees of more than three public companies. The Board has determined that such simultaneous service does not impair Ms. Cholmondeley’s ability to serve effectively on the Audit Committee.

The Audit Committee met seven times in 2005.

The primary duties of the Audit Committee are:

Ø		To assist the Board of Directors in its oversight of (i) the integrity of the Company’s financial statements, (ii) the Company’s compliance with legal and regulatory requirements, (iii) the qualifications and independence of the Company’s independent registered public accounting firm; and (iv) the performance of the Company’s internal audit function and independent registered public accounting firm;
Ø		To appoint, compensate, and oversee the work of any independent registered public accounting firm employed by the Company (including resolution of disagreements between management and the auditors concerning financial reporting) for the purpose of preparing or issuing an audit report or related work. Each such independent registered public accounting firm shall report directly to the Committee; and

To prepare the report of the Committee required by the rules of the Securities and Exchange Commission to be included in the Company’s annual proxy statement.

In addition to its regularly scheduled meetings, the Audit Committee is available either as a group or individually to discuss any matters that might affect the financial statements, internal controls or other financial aspects of the operations of Minerals Technologies Inc. The Chair of the Audit Committee may be reached at the following e-mail address: audit.chair@mineralstech.com.

The Compensation Committee

The Compensation Committee currently consists of Mr. Muscari (Chair), Mr. Curcio, Mr. Dunham, Mr. Golub and Mr. Pasquale, who are not employees of Minerals Technologies Inc. The Board of Directors has determined that each of the members of the Compensation Committee is independent in accordance with the rules of the New York Stock Exchange. The Compensation Committee met seven times in 2005.

The primary duties of the Compensation Committee are:

Ø		To participate in the development of our compensation and benefits policies;
Ø		To establish, and from time to time vary, the salaries and other compensation of the Company’s employee-directors and other elected officers; and
Ø		To participate in top-level management succession planning.

The Chair of the Compensation Committee may be reached at the following e-mail address: compensation.chair@mineralstech.com.

The Corporate Governance and Nominating Committee

The Corporate Governance and Nominating Committee currently consists of Dr. Reid (Chair), Ms. Cholmondeley, Mr. Curcio, Mr. Dunham, Dr. Johnson and Dr. Vallès, who are not employees of Minerals Technologies Inc. The Board of Directors has determined that each of the members of the Corporate Governance and Nominating Committee is independent in accordance with the rules of the New York Stock Exchange. The Corporate Governance and Nominating Committee met six times in 2005.

The primary duties of the Corporate Governance and Nominating Committee are:

Ø		The identification of individuals qualified to become Board members and the recommendation to the Board of nominees for election to the Board at the next annual meeting of stockholders or whenever a vacancy shall occur on the Board;
Ø		The establishment and operation of committees of the Board; and
Ø		The development and recommendation to the Board of corporate governance principles applicable to the Company.

The Corporate Governance and Nominating Committee monitors the composition of the Board to assure that it contains a reasonable balance of professional interests, business experience, financial experience, and independent directors. If the Committee determines that it is in the best interests of the Company to add new Board members, it will consider nominations from several sources, including nominations from sitting members of the Board, search firms and stockholders, made in accordance with the by-laws of the Company. All nominees will be evaluated in accordance with the specific needs of the Board and the Company, as determined from time to time by the Board. The Committee will use its best judgment in recommending to the Board nominees for election, without regard to the source of the nominations.

The Chair of the Corporate Governance and Nominating Committee may be reached at the following e-mail address: governance.chair@mineralstech.com.

COMPENSATION OF DIRECTORS

Fees

Each of the directors, other than Mr. Saueracker, who is the Chief Executive Officer and President of Minerals Technologies Inc., receives an annual retainer fee of $25,000 for serving as a director. Non-employee directors also receive a fee of $2,000 for each meeting of the Board they attend and $1,000 for each committee meeting they attend, except that a director who acts as the chair of a committee receives $1,500 for each committee meeting he or she chairs. Directors also receive compensation under the plans described below.

Nonfunded Deferred Compensation and Unit Award Plan for Non-Employee Directors

Under the Nonfunded Deferred Compensation and Unit Award Plan for Non-Employee Directors, directors who are not employees of Minerals Technologies Inc. have the right to defer their fees. At each director’s election, his or her deferred fees will be credited to his or her account either as dollars or as units which have the economic value of one share of Minerals Technologies Inc. stock. Dollar balances in a director’s account bear interest at a rate of return equal to the rate of return for the Fixed Income Fund in the Minerals Technologies Inc. Savings and Investment Plan. If a director elects to have his or her deferred fees credited to his or her account as units, the number of units credited is calculated by dividing the amount of the deferred fees by the closing price of our common stock as of the last business day prior to the date on which the fees would otherwise be paid.

Each non-employee director is credited with 500 units upon first joining the Board and with an additional 500 units each year as of the date of the Annual Meeting of Stockholders. In addition, non-employee directors serving on the Compensation and Corporate Governance and Nominating committees receive units totaling $6,000 in value each year, while the Chair of these committees receives units totaling $9,000 in value each year. Non-employee directors serving on the Audit Committee receive units totaling $9,000 in value each year, while the Chair of the Audit Committee receives units totaling $15,000 in value each year.

The units in a director’s account are increased by the value of any dividends on our common stock. In the case of cash dividends, the units are increased by a number calculated by multiplying the cash dividend per share times the number of units in the director’s account on the related dividend record date and dividing the result by the closing market price of the common stock on the day prior to the dividend payment date. In the case of stock dividends, the units would be increased by a number calculated by multiplying the stock dividend per share times the number of units in the director’s account on the related dividend record date.

At the time of the director’s termination of service on the Board, the amount held in his or her account is payable in cash only. Based on the director’s prior choice to accumulate dollars or units as described above, the director receives either (i) the amount of his or her deferred fees plus accrued interest, or (ii) an amount determined by multiplying the number of units in his or her account by the closing market price of the common stock on the last business day prior to the date of payment. Payments are made in a lump sum or in installments, at the election of the director.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Mr. Golub, a director of Minerals Technologies Inc., is Managing Director and Vice Chairman of Lazard LLC (“Lazard”). Minerals Technologies Inc. has engaged Lazard to provide investment banking services from time to time with respect to a variety of financial matters. No such services were provided during 2005. Lazard acts as our broker in connection with our ongoing program of repurchases of a portion of our outstanding common stock. To obtain this business, Lazard in an arm’s-length transaction, agreed to meet a competitive bid structured as a fixed commission on each share repurchased. Payments by the Company to Lazard in connection with such brokerage services were approximately $39,550 during 2005.

These transactions were entered into by Minerals Technologies Inc. pursuant to arm’s-length negotiations in the ordinary course of business and on terms that we believe to be fair.

Dr. Vallès, a director of Minerals Technologies Inc., served as a member of the Board of Directors of Pfizer Inc. until June 2005. During 2005, Pfizer Inc. made a series of purchases of precipitated calcium carbonate from Minerals Technologies Inc. totaling $1,684,000. These transactions were entered into by Minerals Technologies Inc. pursuant to arm’s-length negotiations in the ordinary course of business and on terms that we believe to be fair.

REPORT OF THE COMPENSATION COMMITTEE ON
EXECUTIVE COMPENSATION

The Compensation Committee Report, the Audit Committee Report, references to the independence of directors, and the Stock Performance Graph are not deemed to be “soliciting material” or “filed” with the Securities and Exchange Commission, are not subject to the liabilities of Section 18 of the Securities Exchange Act of 1934 as amended (the “Exchange Act”), and shall not be deemed incorporated by reference into any filings previously made or made in the future by our company under the Exchange Act or the Securities Act of 1933, as amended, except to the extent that Minerals Technologies Inc. specifically incorporates any such information into a document that is filed.

The following report of the Compensation Committee of the Board sets forth the Committee’s policies applicable to the executive officers of Minerals Technologies Inc.

	This report is provided by the Compensation Committee of the Board of Directors. The members of the Compensation Committee are independent directors who are not employees of Minerals Technologies Inc., and none serves as a member of the compensation committee of any company that has an executive officer who also serves as a director of Minerals Technologies Inc. The members of the Committee satisfy all applicable requirements for a corporation listed on the New York Stock Exchange and are considered “independent” as that term has been defined by the Exchange.

	The primary purpose of the Compensation Committee is to assist the Board of Directors in the discharge of its responsibilities to the stockholders by overseeing: (1) the executive compensation practices of the Company; (2) administration of the Company’s compensation and benefits programs for employees and non-employee members of the Board; (3) top-level management succession planning; and (4) the production of an annual report on executive compensation for inclusion in the Company’s annual proxy statement. The Committee retains an independent compensation consultant to review and make recommendations regarding the Company’s executive compensation programs. In 2005, the Committee held seven meetings.

Compensation Philosophy

	The Compensation Committee believes that the compensation program for executive officers should reward the achievement of the short-term and long term objectives of Minerals Technologies Inc., and that compensation should be related to the value created for its stockholders. Furthermore, the program should reflect competitive opportunities and best practices in the marketplace.

	The following objectives serve as guiding principles for the Committee:

	Ø		Provide a competitive total compensation opportunity that allows Minerals Technologies Inc. to attract, retain, motivate and reward highly skilled executives;
	Ø		Establish a strong pay-for-performance culture based on the achievement of key business objectives;

	Ø		Provide total remuneration for executives targeted to approximate the third quartile of the marketplace based on the attainment of high levels of performance; and
	Ø		Strengthen the linkage between executive and stockholder interests through the usage of equity awards and executive stock ownership.

The three key elements of this program are (1) annual base salary, (2) short-term incentive bonus opportunity, and (3) long term incentives. In establishing market levels of compensation, the Committee utilizes the services of an independent compensation consulting firm. Market levels are determined based on a review of compensation practices at a comparator group of specialty chemical companies, as well as general industry and chemical industry surveys of similar-sized companies. The comparator group includes the following 15 specialty chemical companies: Albermarle Corporation, Arch Chemicals, Inc., Cabot Corporation, Cytec Industries Inc., Ferro Corporation, H.B. Fuller Corporation, Georgia Gulf Corporation, Great Lakes Chemical Corporation, MacDermid, Inc., NL Industries, Inc., Octel Corporation, Omnova Solutions Inc., A. Schulman, Inc., Spartech Corporation and Wellman, Inc.

Base Pay

	Base salaries are determined in accordance with the responsibilities of each officer, the officer’s tenure in position, performance and market data for the position; though no particular weight is assigned to any one factor. Each employee of Minerals Technologies Inc. receives an annual performance rating. The performance rating of the Chairman, President and Chief Executive Officer is assigned by the Compensation Committee and approved by the Board. The performance ratings of the other elected corporate officers, including those named in the Summary Compensation Table appearing in this Proxy Statement (the “principal executives”), are assigned by the Chairman, President and Chief Executive Officer, subject to review by the Compensation Committee.

	Based on Company performance, general business outlook and industry compensation trends, management each year sets guidelines for corporate-wide average percentage compensation adjustments for all employees for the coming year. The percentage increase received by a particular employee is determined on the basis of the employee’s performance rating and current compensation level compared to similar marketplace positions. In recognition of Company performance in 2005, management recommended, and the Compensation Committee agreed, to make no adjustment in annual base salary at this time for principal executives.

Short Term Incentive Payment

	The Company’s annual incentive component of its overall compensation program is designed to link the pay of senior executives to performance based on goals established at the beginning of each fiscal year. The short-term incentive bonus targets for officers are expressed as a percentage of base salary. Depending upon the extent to which the company’s performance during the year meets targets established earlier by the Compensation Committee, a bonus payment ranging from 0% (for performance of less than 85% of targets) up to 150% of base salary (for performance greater than 120%) is available to the Chief Executive Officer. At 100% of target performance, the 2005 target bonus for the Chief Executive Officer was 75% of salary. The bonus payments can range from 0% up to 120% of base salary for other principal executives. At 100% of target performance, the 2005 target bonus for other principal executives was 60% of salary. These payments, which are made in the following year, are shown as the Bonus for each principal executive in the year to which they are attributable in the Summary Compensation Table included in this Proxy Statement.

	For 2005, Company performance was measured by operating income as compared to target, on a corporate and divisional basis. At the beginning of each year, the Board establishes a target and sets up a performance grid to measure at year-end the extent to which the targets

are met. At year-end, the performance formula is applied to determine the level of the incentive payment to be received by each principal executive. The Committee then considers whether there are other factors that should also be taken into consideration in establishing the overall level of compensation of each principal executive. It will, for example, take into consideration actions that have been taken by management to benefit stockholders in the longer term that may have a negative impact on the factors and annual targets established. For 2005, the Company did not meet the minimum 85% performance threshold required for a payout of the corporate component of the annual incentive program. As a result, no incentive payouts were earned for those principal executives where all or part of incentives were based on corporate results. Partial incentive payouts were earned by certain senior executives based on performance of the Divisions they lead.

Long Term Incentive

The Company’s current long-term incentive program’s design and objectives are to:


	Ø		Provide competitive compensation opportunities that support the business plan of the company;
	Ø		Link pay to both business and stock price performance;
	Ø		Strengthen the linkage between executives and stockholders through share ownership; and
	Ø		Provide strong retention vehicles for key executives.


	Under the 2001 Stock Award and Incentive Plan, the Company makes annual grants to principal executives based on competitive compensation levels and individual performance. The long term incentive program utilizes three vehicles: stock options, performance units, and performance-accelerated deferred restricted stock units (DRSU).

	Three vehicles were utilized again in 2005 as part of the Company’s current long term incentive program in conjunction with the Company’s 2001 Stock Award and Incentive Plan:


	Ø		Stock options;
	Ø		Performance units; and
	Ø		Performance-accelerated deferred restricted stock units (“DRSUs”).


	The target value of individual long term incentive awards granted in 2005 ranged from 70% of base salary up to 265% of base salary for the Company’s ten senior officers. Target values were determined based on Black-Scholes valuation of Company stock options, target payout of performance units and fair market value of DRSUs based on Company stock price. Target awards were determined based on factors such as current role, responsibility, experience, performance ratings for each senior executive, CEO’s assessment of each executive’s potential future impact on Company, competitive compensation opportunities at Company vs. marketplace and the target award’s impact on Company’s financial statements.

Stock Options

In order to focus executives on future stock price appreciation, stock options with an exercise price equal to the fair market value on the date of grant were awarded on February 23, 2005. These options have a ten-year term and vest in equal installments on each of the first three anniversaries from the date of grant. Stock options granted in 2005 represented 20% of the total target long term incentive opportunity awarded to senior executives. This percentage was decreased from 33% in 2004 and 2003 to reflect general marketplace trend of decreasing emphasis on stock options in total remuneration provided to executives.

Performance Units

	In order to focus executives on key long term business performance metrics, performance units were granted in 2005. Performance units vest at the end of a three-year performance period. For the 2005-2007 performance period, the value of each performance unit is dependent on the Company’s average compound annual Net Sales growth and Operating Income Margins. If performance does not meet minimum threshold levels (75% of target), the unit will be worth $0. At target performance, a unit is worth $100 and may be worth up to $300 at maximum performance levels (greater than or equal to 125% of target). The performance unit value is paid out in cash at the end of the performance period. Performance units granted in 2005 represented 40% of the total target long term incentive opportunity awarded to senior executives. This percentage was increased from 33% in 2004 and 2003 to reflect increased focus on key financial performance metrics.

	In 2003, the Committee granted performance units vesting on December 31, 2005 at the end of a three-year performance period with the value tied to the achievement of pre-established goals. Performance units are valued based on average Return on Capital Employed performance over the period. Vested performance units are paid out in cash at the end of the performance period. Based on the Company’s average Return on Capital Employed for the three-year period ending December 31, 2005, 54% of target performance units were earned.

Performance-Accelerated Deferred Restricted Stock Units

In order to align executives’ interests with stockholders and reward superior performance, the Company granted performance-accelerated DRSUs on February 23, 2005. DRSUs vest on the fifth anniversary after the date of grant. Based on performance, DRSUs may vest earlier. 50% of the DRSUs awarded to the executives will vest two years after the date of grant if the Company’s total stockholder return (“TSR”) exceeds the TSR of the S&P Midcap 400 Materials Index over the two-year performance period. All DRSUs will vest three years after the date of grant if the Company’s TSR exceeds the TSR of the S&P Midcap 400 Materials Index over the three-year performance period. Performance-accelerated DRSUs granted in 2005 represented 40% of the total target long term incentive opportunity awarded to senior executives. This percentage was increased from 33% in 2004 and 2003 to further align executives’ interests with stockholders, reward superior performance and increase retention. The vesting of DRSUs granted in 2003 and 2004 did not accelerate in 2005 based on TSR performance.

Share Retention Requirements

To further align the interests of management with the Company’s stockholders, the Committee established share retention requirements in connection with the 2005 long term incentive awards. 50% of the after-tax value of stock option exercise gains must be held in Company stock for a minimum of five years following exercise. In addition, 50% of any Company stock issued following the vesting of DRSUs must be retained by the recipient for a minimum of five years.

2005 Compensation For The Chief Executive Officer

In January of 2005, Mr. Saueracker received a salary increase to $675,000. This amount was made in consideration of his demonstrated leadership of the Company and competitive marketplace pay levels. As mentioned previously, due to the lack of achieving the specified threshold corporate Operating Income target in 2005, Mr. Saueracker did not receive an annual bonus. In connection with the 2005 long term incentive program, Mr. Saueracker received a target long term award value equal to 265% of salary. The long term awards consisted of a stock option grant of 17,300 shares, 7,200 performance units and 11,700 DRSUs.

	As part of the 2003 performance unit grant previously described, in 2006 Mr. Saueracker received $195,600 (54% of target) based on the Company’s average Return on Capital Employed. In 2005, accelerated vesting of DRSUs based on TSR performance did not occur.

	In addition, the Committee also reviewed the total compensation program for Mr. Saueracker, including pension benefits and the potential payments due upon termination under various scenarios.

	At his request, Mr. Saueracker’s annual base salary was not increased in January 2006. This is in spite of the fact that Mr. Saueracker’s salary continues to be below targeted market levels.

Discretionary Authority Of The Committee

The Compensation Committee believes that the application of the procedures described above will generally result in fair and adequate compensation to each principal executive. However, the Compensation Committee also believes that no arbitrary formula is an adequate substitute for individual judgments in all cases, particularly in determining the value of a principal executive’s contribution to the success of the company. Therefore, the Committee may from time to time use its discretion in deviating from the above procedures (including, possibly, modifying the factors discussed above or varying their weighting) to set compensation levels for the principal executives and others that best serve the interests of the company and its stockholders.

Internal Revenue Code Section 162(m)

Internal Revenue Code Section 162(m) and regulations thereunder, which limit the deductibility of certain executive compensation in excess of $1,000,000, did not result in any disallowance of a deduction for compensation payments made by Minerals Technologies Inc. for the 2005 fiscal year. However, the Committee has determined that, in order to retain the discretion referred to in the previous paragraph; it reserves the right to make compensation payments that in part may not qualify for a tax deduction because of the limitations of Internal Revenue Code Section 162(m).

EMPLOYMENT, TERMINATION AND CHANGE-IN-CONTROL ARRANGEMENTS

Employment Agreements

In January 2002, Minerals Technologies Inc. entered into employment agreements with the following individuals for the indicated terms and for not less than the annual base salaries indicated: Mr. Saueracker, 24 months, $550,000; Mr. Sorel, 18 months, $265,000; Mr. Massimine, 18 months, $240,000; in November 2002 with Mr. Bouruet-Aubertot, 18 months, $250,000; and in November 2004, with Mr. Forrest, 18 months, $270,000. The term of each of these agreements is extended on the first day of each month for an additional month, unless either the employee or the employer gives the other written notice that the agreement should not be further extended. Each of the named executive officers may also receive salary increases and annual bonuses in amounts to be determined by the Board or the Compensation Committee. The agreements also entitle the named executive officers to participate in employee benefit plans and other fringe benefits that are generally available to our executive employees.

Under the agreements, each named executive officer has agreed to comply with certain customary provisions, including covenants not to disclose our confidential information at any time and not to compete with our business during the term of the agreement and, subject to our continued payment of amounts under the agreement, for two years thereafter. We may terminate the employment agreements before the end of the specified term of employment for “cause” as defined in the agreements.

Severance Agreements

Minerals Technologies Inc. has entered into severance agreements with certain of its executive officers, including each of the named executive officers. The agreements continue through December 31 of each year, and are automatically extended in one-year increments unless we choose to terminate them. If a change in control occurs, the severance agreements are effective for a period of four years from the end of the then existing term. These agreements are intended to provide for continuity of management in the event of a change in control of Minerals Technologies Inc.

If, following a change in control, the executive is terminated by Minerals Technologies Inc. for any reason, other than for disability, death, retirement or for cause (as defined in the agreements), or if the executive terminates his or her employment for good reason (as defined in the agreements), then the executive is entitled to a severance payment of 2.99 times the executive’s base amount (as defined in the agreements). The severance payment generally will be made in a lump sum. For a period of up to two years following a termination that entitles an executive to severance payments, Minerals Technologies Inc. will provide life, disability, accident and health insurance coverage substantially similar to the benefits provided before termination, except to the extent such coverage would result in an excise tax being imposed under Section 4999 of the Internal Revenue Code.

The agreements also provide that upon the occurrence of certain stated events that constitute a “potential change in control” of Minerals Technologies Inc., the executive agrees not to voluntarily terminate his employment with Minerals Technologies Inc. for a six-month period.

Under the severance agreements, a change in control includes any of the following events unless approved by the Board: (i) we are required to report a “change in control” in accordance with the Securities Exchange Act of 1934; (ii) any person acquires 15% of our voting securities; (iii) a majority of our directors are replaced during a two-year period; or (iv) our stockholders approve a merger, liquidation or sale of assets.

2001 Stock Award and Incentive Plan

The 2001 Stock Award and Incentive Plan provides that the Compensation Committee may exercise its discretion to accelerate the vesting of awards upon the employee’s retirement or upon a change in control of Minerals Technologies Inc. (as defined in the plan).

Retirement Plans

Each of the named executive officers is entitled to benefits under the defined benefit pension plans which we maintain. The Retirement Plan is a tax qualified pension plan which pays retirement benefits within the limits prescribed by the Internal Revenue Code. The Nonfunded Supplemental Retirement Plan is an unfunded, non-tax qualified pension plan which pays retirement benefits in excess of such Code limits. For employees hired prior to January 1, 2002, benefits under the Retirement Plan and the Nonfunded Supplemental Retirement Plan are based upon an annuity equal to the greater of (i) 1.4% of a participant’s career earnings or (ii) 1.75% of a participant’s career earnings less 1.5% of primary Social Security benefits, multiplied by years of service up to 35 years. For purposes of this formula, a participant’s “career earnings” are based on the average earnings for the five highest consecutive calendar years prior to January 1, 1998, and on actual earnings for periods after December 31, 1997. For employees hired after January 1, 2002, benefits under the Retirement Plan and the Nonfunded Supplemental Retirement Plan are based upon a cash balance formula which credits such employees with annual pay credits equal to the employee’s pensionable earnings for the year multiplied by 5%. An employee’s cash balance account will also receive “interest credits” each year, based on a market rate of interest declared at the end of each year.

Under the Retirement Plan and the Nonfunded Supplemental Retirement Plan, each of the named executive officers would be entitled to the following annual benefits after retirement: Mr. Saueracker, $202,862; Mr. Sorel, $151,712; Mr. Massimine, $114,528; Mr. Bouruet-Aubertot, $56,287 and Mr. Forrest, $16,561. This assumes that (i) payments will be made in the form of a 50% joint and survivor annuity; (ii) employment will be continued until normal retirement at age 65; and (iii) creditable compensation will continue at 2005 levels until retirement.

Grantor Trust

In order to secure the benefits accrued under the Nonfunded Supplemental Retirement Plan and the Nonfunded Deferred Compensation and Supplemental Savings Plan (an unfunded, non-tax qualified plan which pays amounts in excess of the limits which the Internal Revenue Code imposes on benefits under our Savings and Investment Plan), Minerals Technologies Inc. has entered into an agreement establishing a grantor trust within the meaning of the Internal Revenue Code. Under the Grantor Trust Agreement, we are required to make certain contributions of cash or other property to the trust upon the retirement of individuals who are beneficiaries of those plans; upon the occurrence of certain events defined as constituting a “Change of Control” and in certain other circumstances.

Option Grants in Last Fiscal Year

This table provides information on options granted to all of the named executive officers on February 23, 2005. The last two columns of the table show the potential realizable value of the options in each of two hypothetical cases. The first case assumes that the price of the stock increases at a rate of five % per year over the term of the options, which, in the case of the February 2005 grants, would result in a price of approximately $100.89 per share in 2015 and an increase in aggregate stockholder value of approximately $779 million. The second case assumes that the price of the stock increases at a rate of 10% per year over the term of the options, which, in the case of the February 2005 grants, would result in a price of approximately $160.66 per share in 2015 and an increase in aggregate stockholder value of approximately $1,973 million. The actual market value of the stock at any future date may, or may not, correspond to any of these hypothetical cases.

Long Term Incentive Plan Awards in Last Fiscal Year

The following table gives information concerning the participation of the named executive officers in the Company’s long term incentive plan as governed by the 2001 Stock Award and Incentive Plan. Under this plan, the named executive officers and certain other executives were awarded units whose value will be determined based on a non-discretionary formula which measures our performance over a three-year period using performance goals that were determined by the Compensation Committee and approved by the Board. The formula is based on the target growth in sales and operating income employed over the three-year period. If our performance is below the threshold level set forth in the plan, the value of the units will be zero. To the extent the Company’s performance exceeds the threshold performance level, the value of the units will increase up to the maximum amount of $300 per unit. The plan is also discussed in the Report of the Compensation Committee above.

					Estimated Future Payouts Under Non-Stock Price-Based Plans(1)

(1)		The actual value of units that will be paid out at the end of the performance period, if any, cannot be determined because the value of units will be based upon the Company’s future growth in sales and operating income. If the Company’s performance is below the established threshold performance levels, then the value of the units will be zero. To the extent the Company’s performance exceeds the threshold performance level, the units will increase in value.

(2)		The threshold amount of each unit is $50.

(3)		The target amount of each unit is $100.

(4)		The maximum amount of each unit is $300.

ITEM 2—RATIFICATION OF APPOINTMENT OF AUDITORS

The Audit Committee of the Board has appointed KPMG LLP to serve as our independent registered public accounting firm for the current fiscal year, subject to the approval of the stockholders. KPMG LLP and its predecessors have audited the financial records of the businesses that comprise Minerals Technologies Inc. for many years. We consider the firm well qualified.

We expect that representatives of KPMG LLP will be present at the Annual Meeting of Stockholders. These representatives will have the opportunity to make a statement if they wish to do so, and will be available to respond to appropriate questions.

The Board of Directors unanimously recommends a vote FOR ratification of the appointment of KPMG LLP as our independent registered public accounting firm for the 2006 fiscal year.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee assists the Board of Directors in fulfilling its responsibility for oversight of the quality and integrity of the accounting, auditing and reporting practices of the Company. The Audit Committee operates in accordance with a written charter, which was adopted by the Board. A copy of that charter is attached as Appendix 1 to this Proxy Statement.

As part of fulfilling its oversight responsibility, the Audit Committee reviewed and discussed with management the audited financial statements of the Company, including the audit of management's assessment of, and the effective operation of, internal control over financial reporting, for the fiscal year ended December 31, 2005. In addition, the Audit Committee discussed with the Company's independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards No. 61, as amended, “Communication with Audit Committees.”

The Audit Committee obtained from the independent registered public accounting firm a formal written statement describing all relationships between the auditors and the Company that might bear on the auditors' independence, consistent with Independence Standards Board Standard No. 1, “Independence Discussions with Audit Committees,” and discussed with the auditors any relationships that may impact their objectivity and independence.

Principal Accounting Fees And Services

The Company incurred the following fees for services performed by KPMG LLP in fiscal years 2005 and 2004:

	2005		2004
Audit Fees	$	2,573,000	$	2,604,000
Audit Related Fees		67,000		337,500
Tax Fees		95,000		249,500
All Other Fees		—		—

Total Fees	$	2,735,000	$	3,191,000

Audit Fees. Audit fees are fees the Company paid to KPMG LLP for professional services for the audit of the Company's consolidated financial statements included in the Annual Report on Form 10-K, including fees associated with the audit of management's assessment of, and the effective operation of, internal control over financial reporting, and review of financial statements included in Quarterly Reports on Form 10-Q, or for services that are normally provided by the independent registered public accounting firm in connection with statutory and regulatory filings or engagements.

Audit Related Fees. Audit related fees are billed by KPMG LLP for assurance and related services that are reasonably related to the audit or review of the Company's financial statements, including due diligence and benefit plan audits.

Tax Fees. Tax fees are fees billed by KPMG LLP for tax compliance, tax advice and tax planning.

All Other Fees. All other fees are fees billed by KPMG LLP to the Company for any services not included in the first three categories.

Pre-Approval Policy. During fiscal year 2005, the Audit Committee established a policy to require that it approve all services provided by its independent registered public accounting firm before the independent registered public accounting firm provides those services. The Audit Committee has pre-approved the engagement of the independent registered public accounting firm for audit services, audit-related services, tax services and all other fees within defined limits. The percentage of fees paid to KPMG LLP for services that were approved by the Audit Committee in accordance with its pre-approval policy is 100% with respect to fiscal year 2005.

The Audit Committee considered all these services in connection with KPMG LLP's audits of the Company's financial statements, management's assessment of internal control over financial reporting, and the effective operation of internal control over financial reporting for the fiscal years ended December 31, 2005 and 2004, and concluded that they were compatible with maintaining KPMG LLP's independence from the Company in the applicable periods.

Based upon the review and discussions referred to above, the Audit Committee recommended to the Board that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2005, for filing with the Securities and Exchange Commission.

APPENDIX 1

CHARTER OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS
OF MINERALS TECHNOLOGIES INC.

I. PURPOSE

The primary purposes of the Audit Committee (the “Committee”) are to:

	1.		Assist the Board of Directors (the “Board”) in its oversight of (i) the integrity of the Company’s financial statements, (ii) the Company’s compliance with legal and regulatory requirements, (iii) the qualifications and independence of the Company’s independent auditor; and (iv) the performance of the Company’s internal audit function and independent auditor;
	2.		Appoint, compensate, and oversee the work of any registered public accounting firm employed by the Company (including resolution of disagreements between management and the auditor concerning financial reporting) for the purpose of preparing or issuing an audit report or related work. Each such registered public accounting firm shall report directly to the Committee; and
	3.		Prepare the report of the Committee that the rules of the Securities and Exchange Commission (the “Commission”) require be included in the Company’s annual proxy statement.

To fulfill these purposes, the Committee shall have the powers and responsibilities enumerated in Sections IV and V, below, and shall be provided by the Company with appropriate funding for (i) compensation of any registered public accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services for the Company; (ii) compensation of any advisers employed by the Committee under item 32 of Article V, below; and (iii) ordinary administrative expenses of the Committee that are necessary and appropriate in carrying out its duties.

II. MEMBERSHIP

The Committee shall be composed of three or more directors as determined by the Board, each of whom shall be independent and free from any relationship that, in the opinion of the Board, would interfere with the exercise of his or her independent judgment as a member of the Committee. For purposes of determining whether or not a director is independent, the Board shall, at a minimum, apply the standards set forth in Section 303A of the Listed Company Manual of the New York Stock Exchange (the “NYSE Manual”) and Section 301 of the Sarbanes-Oxley Act of 2002 (the “Act”). All members of the Committee shall have a working familiarity with basic finance and accounting practices and must be financially literate, as such qualification is interpreted by the Board, and at least one member of the Committee shall be an “audit committee financial expert” as defined by the Commission. Committee members may enhance their familiarity with finance and accounting by participating in educational programs. No member of the Committee may serve on the audit committees of more than three public companies, including the Committee unless the Board determines that such simultaneous service does not impair such member’s ability to serve effectively on the Committee.

The members of the Committee shall be elected by the Board at the annual organizational meeting of the Board, and at such other times as vacancies may occur, and shall serve until the next annual organizational meeting of the Board or until their successors shall be duly elected and qualified.

III. MEETINGS

The Committee shall meet at least four times annually, or more frequently as circumstances dictate. As part of its job to foster open communications, the Committee should meet at least annually with management, the director of the internal auditing department, and the independent auditor in separate executive sessions to discuss any matters that the Committee or any of these groups believe should be discussed privately. In addition, the Committee, or at least the Chair, should meet with the independent

A-1
