DOMESTIC PRODUCTION
Talc
U.S. mine production o f crude talc increased 7% in tonnage and 1% in value. Talc and soapstone were pro duced at mines in 10 States. Mines that operated in M ontana, New York, Texas, and Vermont accounted for 92% o f dom estic talc production. M ontana led all States in the tonnage and value o f talc produced. M ontana Talc Co. applied for operating permits for a pro-
Dom estic production and sales data for talc and pyrophyllite are developed by the Bureau o f Mines from a volun tary survey o f U.S. mines and mills. O f the 52 mines and mills to which a survey request was sent, 32 responded, representing 62% o f the U.S. produc tion data shown in table 1. Production for the 20 nonrespondents was esti mated using reported prior-year pro duction levels adjusted by trends in employment and other guidelines.
LEGISLATION AND GOVERNMENT PROGRAMS
The Occupational Safety and Health Administration (OSHA) extended through July 21, 1989, an administrative stay on its 1986 regulation governing worker exposure to the nonasbestiform varieties o f actinolite, anthophyllite, and tremolite. During the stay, OSHA con tinued to analyze the impact o f using the asbestos standard to regulate the nonas bestiform varieties o f the minerals. An exposure limit o f 2 fibers per cubic cen timeter will remain in effect during the stay.2
OSHA also proposed revisions to air contaminant standards. The proposed ruling establishes or m odifies exposure lim its for more than 300 substances, including soapstone and nonasbesti form talc. Permissible exposure limits o f 6 and 3 milligrams per cubic meter

posed mine about 12 miles southeast of Dillon, MT. The company planned to produce approximately 624,000 short tons of ore over an 8-year period.4
Cyprus Industrial Minerals Inc. com pleted its acquisition of Vermont Talc Co. The purchase of Vermont Talc in cluded one mine in Windham, one mine near Troy, a mill in Chester, and a flota tion mill in Johnson. Cyprus Industrial Minerals indicated that pharmaceutical-, paint-, paper-, and plastic-grade talc can be produced at the Johnson site and industrial-grade talc can be produced at the Chester site.5
The company also completed its ac quisition of Windsor Minerals Inc., a m ajor talc producing company in Ver mont. Windsor Minerals owns several mines and two mills. The company produces cosmetic- and industrial grade talc.6

END USES FOR GROUND TALC AND PYROPHYLLITE
(Thousand short tons)
Pyrophyllite Pyrophyllite was produced by four
companies operating six mines in Cali fornia and North Carolina. Production increased 16Vo over that of 1987.
CONSUMPTION AND USES
Apparent domestic consumption of crude and processed talc and pyrophyl lite increased 3%. Sales of talc and pyrophyllite increased 5% in tonnage and 6% in value.
End-use distribution of ground talc was ceramics, 34Vo; paint, 14Vo; paper, 13Vo; roofing, 11Vo; plastics, lOVo; cos metics, 5Vo; and insecticides, refracto ries, rubber, and other, 13Vo. The largest portion, 55Vo, of domestically produced ground pyrophyllite was used in ceram ics; 14Vo in refractories, 7Vo in insecti cides, and 24Vo in paint, plastics, roof ing, rubber, and other.

FOREIGN TRADE
Talc exports increased 32% in ton nage and 38% in value. Mexico re mained the largest importer of talc, followed by Canada, BelgiumLuxembourg, and Japan. Favorable ex change rates and slightly increased us age in Europe resulted in increased exports to Belgium. Exports to Mexico also increased in 1988.
Talc imports increased 64% in tonnage and 19% in value. Australia and Canada provided 77% of all talc imports.
WORLD CAPACITY
The data in table 6 are annual rated capacity for mines and refineries as of December 31, 1988. Rated capacity is defined as the maximum quantity of product that can be produced in a period of time on a normally sustain able long-term operating rate, based on the physical equipment of the plant, and given acceptable routine operating procedures involving labor, energy, ma terials, and maintenance. Capacity in cludes both operating plants and plants temporarily closed that, in the judgment of the author, can be brought into pro duction within a short period of time with minimum capital expenditure.
WORLD REVIEW
The United States remained the world's largest talc producer, and Japan remained the largest pyrophyllite pro ducer. China, Japan, and the United States accounted for 46% of the world's talc and pyrophyllite production.
Cyprus Industrial Minerals completed its acquisition of Distribuidora Mala guea de Talcos S.A. (DIMTASA). DIMTASA owned surface mines and a mill near Mlaga, Spain. Cyprus Indus trial Minerals will process high-value talc from Australia and the United States at the Mlaga mill for the paint, paper, and plastics industries. The company will continue to sell talc from the Malaga mine to industrial markets in northern and southern Europe.7
TECHNOLOGY
In modernizing its mines in Italy, Talco e Grafite Val Chisone Co. in creased production capabilities by changing from an overhand cut-and-fill method to an underhand horizontal slicing method with cemented backfill. To take advantage of the increased pro duction capabilities, the company in vestigated electrically powered, rubbertired loaders as replacements for compressed-air-powered rocker shovels and battery-powered trains as a means of improving the efficiency of ore load ing and transport. The change from rocker shovels and trains to rubbertired loaders resulted in greater safety for the miners, less dust because of the absence of compressed air exhaust, fewer loading maneuvers, lower noise levels, and a 32% reduction in the production cost per ton.8
