TALC AND PYROPHYLLITE
By Robert L. Virta
CAM-297
Mr. Virta, a physical scientist with 15 years of U.S. Bureau of Mines experience, has been the commodity specialist for talc and pyrophyIlite since 1986. Domestic suney data were prepared by Linder Roberts, mineral data assistant; and international data tables were prepared by William Zajac, Chief, Section, International Data.
D omestic production of talc and pyrophyllite increased slightly from that of 1989 to 1,267,167 metric tons. Sales of crude and processed talc decreased 4070 to 1,021,004 tons in tonnage and decreased 3% in value. Sales of pyrophyllite increased slightly. Imports for consumption decreased 17% in tonnage to 65,099 tons and decreased 9% in value to $11,056,000. Exports decreased 25% in tonnage to 238,000 tons and increased 14% in value to $32,909,000. During the past 10 years, talc and pyrophyllite production averaged 1,075,000 tons; sales, 972,000 tons; domestic consumption, 948,000 tons; exports, 242,000 tons; and imports, 49,000 tons. The major use for talc was in ceramics, which accounted for 28% of the domestic consumption, followed by paint, 18%; paper, 17%; roofing, 11 %; plastics, 6%; and other, 20%. The major use for pyrophyllite was in ceramics, followed by refractories, insecticides, paint, plastics, and rubber.
DOMESTIC DATA COVERAGE
Domestic production and sales data for talc and pyrophyllite are developed by the U.S. Bureau of Mines from a voluntary survey of U.S. mines and mills. Survey forms were sent to 18 companies that operated 52 mines and mills. Seventeen companies that account for approximately 99% of the domestic production responded to the survey. Production data for the nonrespondent were estimated from reported prior-year production levels adjusted by trends in employment and other guidelines.
ANNUAL REVIEW
Legislation and Government Programs
The Occupational Safety and Health Administration (OSHA) extended an administrative stay on its 1986 regulation governing worker exposure to the nonasbestiform varieties of actinolite, anthophyllite, and tremolite through
August 31, 1991. During the stay, OSHA continued to analyze the impact of using the asbestos standard to regulate the nonasbestiform varieties of the minerals. An exposure limit of two fibers per cubic centimeter will remain in effect during the stay. 1
The Mine Safety and Health Administration (MSHA) continued to review its proposed revisions to its air quality, chemical substances, and respiratory pro-

tection standards. The proposed permissible 8-hour time weighted average exposure limit is 2.S milligrams per cubic meter for talc (containing no asbestos), 3 milligrams per cubic meter for respirable soapstone, and 6 milligrams per cubic meter for total soapstone dust. The nonasbestiform varieties of tremolite, anthophyllite, and actinolite would be covered under the proposed respirable mine dust standard.2
MSHA issued a proposed rule that would create a hazard communication standard. Mine operators would be required to provide information to their employees concerning any hazards that chemicals, including talc, produced or used on the premises through labeling, material safety data sheets, and employee training.3
Issues
The health risk posed by nonasbestiform varieties of tremolite, anthophyllite, and actinolite continued to be a concern for a portion of the talc industry. OSHA is evaluating whether to regulate the nonasbestiform amphiboles as asbestos, regulate nonasbestiform amphiboles under a separate standard, or not to regulate nonasbestiform amphiboles.
Production
1illc.-Thirteen companies operating 22 mines in 10 States produced talc, soapstone, and steatite. These companies generally were structured to cover all aspects of talc mining, from mining to processing. Only a few companies hired custom grinders to mill the ore. The largest of the domestic producers were Cyprus Industrial Minerals Co. Inc., Dal Minerals, Gouverneur Talc Co., Montana Talc Co., and PfIZer Inc. The major producing deposits were in Montana, New York, Texas, and Vermont.
Commercial talc production was from deposits that were formed through hydrothermal alteration of ultrabasic rocks and low-grade metamorphism of siliceous dolomites. They generally occur as lenses or pods in the country rock. Magnesite, quartz, chlorite, magnetite, serpentine, anthophyllite, tremolite, dolomite, and actinolite may be present as accessory minerals.
Most of the domestic talc production was from open pit mining operations. Underground mining was used only
1142
when a large waste rock to ore ratio made open pit mining uneconomical. Typically, overburden was removed, and blasting was 'used to fracture the ore. The companies then used selective mining and manual or automated sorting to produce a high-grade feed for the mill. Jaw crushers were used to reduce the size of the mill feed, and ball mills or roller mills were used to produce the final product. Fluid-energy mills or pulverizing mills were used for ultrafine grinding of the talc ore. In a few instances, the ore was calcined prior to milling to increase its whiteness.
Flotation processes were used when the desired product purity was not obtained by using conventional processing. The milled ore was chemically treated, passed through rougher and cleaner cells to separate the talc from the gangue material, dried in a flash dryer, and ground in a pulverizer. Ore composition, reagent type, pulp density, pH of the flotation system, and residence time in the flotation circuits determined flotation efficiency.
Cyprus Industrial Minerals Co. announced that it would close its Hammondsville mine. The decision to close the underground mine, which has operated for about 40 years, was made for safety and economic reasons,4
U.S. mine production of crude talc increased slightly in tonnage and 12% in value. Mines that operated in Montana, New York, Texas, and Vermont accounted for 96070 of domestic talc production. Montana led all States in the tonnage and value of talc produced.
Pyrophyllite.-Pyrophyllite was pro-
duced by three companies operating four mines in two States. Production was from hydrothermally altered volcanic deposits of acidic composition. The deposits consisted of pyrophyllite with sericite, andalusite, and/or quartz as accessory minerals. After removing the
overburden, the ore was either stripped
using dozers and scrapers or extracted using conventional open pit mining
techniques. The ore was dried, and
then jaw crushers and gyratory crushers were used to reduce the size of the mill feed. Ball, pebble, or roller mills were used to produce the final product.
U.S. mine production of crude pyrophyllite increased slightly in tonnage. North Carolina accounted for most of the domestic production.
Consumption and Uses
7il1c.-Talc was used in a wide variety of products because of its softness (1 on the Mohs scale), purity, fragrance retention, whiteness, luster, moisture content, oil and grease adsorption, chemical inertness, low electrical conductivity, high dielectric strength, and high thermal conductivity. These properties were not universal to all talcose materials because of differences in their mineralogical composition and particle shape. Mineral content was extremely important because it determined the end use for the material. Generally, onlytwo or three of these properties were critical for anyone application.
Talc was used as a filler in polypropylene compounds. It served to improve the modulus and impact strengths of the product, improve the stability of the

product under ultraviolet light, and reduce the price of the fmal product. Products had higher modulus and impact strengths, higher deflection temperatures under load, and lower coefficient of thermal expansion when finely ground talc was used with high crystallinity polypropylene.S
Domestic producers reported that overall sales (including direct exports) declined 4070 in tonnage to 1,021,004 tons and 3% in value to $110,584,808 in 1990. The major consumer of talc was the construction industry, with applications in ceramic tiles and sanitary-
ware, joint compounds, paint, plastics,
and roofing. The end-use distribution was ceramics, 28%; paint, 18%; paper, 16%; roofing, 11 %; plastics, 6%; cosmetics, 4%; and insecticides, refractories, rubber, and other, 17%. The greatest decrease in demand was in ceramics, cosmetics, and plastics applications. Some decline was expected due to a sluggish US. economy, but it is doubtful that the entire decrease can be attributed to a sluggish economy. It is likely that some sales to the ceramic, cosmetic, and plastic industries were reported under the "Other" category, which increased in 1990. More than 90% of the companies responded to the end-use portion of the 1990 annual survey, representing approximately 95% of the data in table 3.
Pyrophyllite.-Pyrophyllite, being different in composition from talc, did not have the same applications as talc. Properties such as softness (1 to 2 on the Mohs. scale), whiteness, chemical inertness, high melting point, low electrical conductivity, and high dielectric strength made pyrophyllitic materials useful for ceramics and refractories.
US. consumption of pyrophyUite increased slightly in tonnage in 1989. The largest portion of domestically pro-
duced ground pyrophyUite was used in
ceramics, followed by refractories, insecticides, paint, plastics, and rubber. The end-use distribution did not change significantly from previous years.
Markets and Prices
Talc prices varied depending on the quality and on the degree and method of processing. The unit value of crude talc was $25 per ton. The average unit
value of processed talc was $108 per
ton. The average unit values of crude

and processed pyrophyllite were higher in 1990 than in 1989. Unit values for imported crude and ground talc ranged from $33 per ton to $410 per ton for quantities greater than 100 tons. The average unit value for all imported talc
was $170 per ton. Unit values for ex-
ported talc ranged from $16 per ton to $1,576 per ton for quantities greater than 100 tons and averaged $138 per ton for all exports.
Prices, quoted by the American Paint & Coatings Journal, December 26, 1990, in US. dollars per metric ton for paintgrade talc in carload lots ranged from $99 to $243. Approximate equivalents, in dollars per metric ton, of price ranges quoted in Industrial Minerals (London), December 1990, for talc, c.i.f. main European ports, ranged from $165 to $336.
Foreign liade
Talc exports decreased 25% in tonnage and increased 14% in value. Mexico remained the largest importer of talc, followed by Canada, Japan, and Belgium-Luxembourg. Talc imports decreased 17% in tonnage and 9070 in value. Australia and Canada provided 82% of all talc i~ports.
World Review
The United States remained the world's largest talc producer, and Japan
remained the largest pyrophyllite producer. China, Japan, and the United States accounted for 43% of the world's talc and pyrophyllite production.

TALC AND PYROPHYLLITE-I990
talc in Australia and East Asia was reviewed. The paper focussed on highquality deposits in Australia, China, and the Republic of Korea, whose producers account for approximately onethird of the world's talc production. The region possesses large reserves, high-quality deposits, and a good location with regard to growing markets, although technological deficiencies and supply reliability are weaknesses of the industry.6
Capacity.-The data in table 6 are annual rated capacity for mines and refineries as of December 31, 1990. Rated capacity is defined as the maximum quantity of product that can be produced in a period of time on a normally sustainable long-term operating rate, based on the physical equipment of the plant, and given acceptable routine operating procedures involving labor, energy, materials, and maintenance. Capacity includes both operating plants and plants temporarily closed that, in the judgment of the author, can be brought into production within a short period of time with minimum capital expenditure.
Australia.-South Australia supplied most of the talc for Australia's domestic demands despite accounting for only 9% of Australia's total production. Production comes primarily from the Mount Fitton deposit, 470 miles north of Adelaide. The Mount Fitton deposit was formed through the hydrothermal alteration of dolomite and marble rocks. It is 10 to 15 meters wide, 20 meters high, and several hundred meters long. Conventional open pit methods are used to mine the deposit. Approximately 700/0 of production is used in pharmaceutical and paint products.'
lreland.-Ivernia West PLC acquired a major shareholding in Talc Technology Ltd., owner of the Westport talc deposit. The talc deposit is composed of 50% talc, 33% breunerite, 10% antigorite, 2% dolomite; and 5% magnesite and contains approximately 5.5 million tons of talc. If development permits are approved, the mine production initially will be 40,000 tons per year.8
Sweden.-Handols Taljstens AB, now under private ownership, produces approximately 20,000 tons of talc-

chlorite for animal feed, roofing, plastics, and fertilizers. Research is being conducted to separate talc from chlorite through flotation processing. The processed talc will be suitable for paper applications. Primary tests indicate that the talc can be upgraded from 60% talc
to 97% talc with a brightness of 92% to 93%.9
Venezuela.-A talc deposit was discovered on Margarita Island, off the coast of Venezuela. Further investigations are being carried on the commercial viability of the deposit. Venezuela currently does not produce talc. JO
Current Research The flotation process can be better
controlled with the use of on-line monitoring. On-line processing enables the operator to immediately detect changes in the operation and make the necessary adjustments to ensure a constant product quality. X-ray fluoresence is used to determine elemental compositions of the flotation slurry at various stages in the flotation process. Greater control is obtained when coupled with on-line brightness determinations. 1I
The use of column flotation to process industrial minerals was reviewed. The paper discussed the processing of andalusite, chromite ore, fluorite, graphite, manganese. oxide ore, phosphate ore, potash, and talc. A talc ore composed of 50% talc and ground to 80% less than 45 micrometers was upgraded to 73% talc by using two stages of column flotation. This result is a 6% improvement over conventional flotation using five stages. A Korean talc ore composed of 73% talc and ground to less than 45 micrometers was upgraded to 83% by using a single stage of column flotation. Recovery of the same ore using three stages of conventional flotation was 45% to 65%.12
OUTWOK
The average annual growth in domestic demand for talc and pyrophyllite was 1.2% between 1981 and 1990. Demand averaged between 900,000 and 1,000,000 tons per year for this period. Relative increases and decreases in demand have been the result of minor market fluctuations rather than longterm trends. Demand for talc and pyrophyllite is expected to continue to fluctuate around 1 million tons per year in the near future.
Ceramics will continue to be the major domestic end use for talc, followed by consumption in paint, paper, plastics, roofing, and cosmetics, in de-

major domestic end uses will continue
to be in ceramics and refractories.
