Published on an annual basis, this report is the earliest Government publication to furnish estimates covering nonfuel mineral industry data. Data sheets contain information on the domestic industry structure, Government programs, tariffs, and 5-year salient statistics for over 90 individual minerals and materials.
Part of a special section on industrial minerals. Gemstone production, consumption and uses, prices, imports and exports are discussed, and the future of the gemstone industry is considered.
In 2001, one mine in Utah produced a small quantity of fluorspar. The majority of fluorspar consumed in the United States continued to come from imports or material purchased from the US National Defense Stockpile (NDS). In addition, a small amount of synthetic fluorspar (CaF2) was produced from industrial waste streams.
Seawater and natural brines accounted for about 60% of US magnesium compounds production in 2001. Dead-burned and caustic-calcined magnesias were recovered from seawater in Florida by Premier Chemicals. They were also recovered from Michigan well brines by Dow Chemical, Martin Marietta Magnesia Specialties and Rohm & Haas. And Premier Chemicals recovered dead-burned and caustic-calcined...
A general overview of the industrial garnet industry is provided. About 20 percent of global industrial garnet production takes place in the U.S. During 2000, an estimated 300 kt of industrial garnets were produced worldwide. The U.S. is the world's largest consumer of industrial garnet, consuming 56.9 kt in 2000.
Part of the 2000 annual review of the industrial minerals sector. A general overview of the common clay and shale industry is provided. In 2000, U.S. production increased by 5 percent, while sales or use declined to 23.6 Mt. Despite the slowdown in the economy, no major changes are expected for the market.

Part of an annual review of mines and mineral resources in the U.S. An overview of nonfuel-mineral exploration in 2000 is presented. Principal exploration target was gold exploration in Latin America, Australia, and the U.S. There was a decrease of 18 percent in the exploration budget for gold as compared with the budget for 1999. Statistical information on nonfuel-mineral exploration...
Seawater and natural brines accounted for about 63% of US magnesium compounds production during 2000. Premier Services in Florida, Dow Chemical in Michigan, Martin Marietta Magnesia Specialties, and Rohm & Haas recovered dead-burned and caustic-calcined magnesias from seawater. And Premier Services' recoveries, in Nevada, were from magnasite.
Part of the 2000 annual review of the industrial minerals sector. A general overview of the gemstones industry is provided. Although no extensive commercial mining of gemstones takes place in the U.S., it is the world's leading gemstone market. Total U.S. gemstone trade exceeded $16.9 billion in 2000.
US ammonia production in 2000 declined by about 7% from 1999. The largest decline occurred in the second half of the year. High natural gas prices caused many plants to close or curtail production near the end of the year. By year-end, about one-third of the US ammonia production capacity was shut down.
A general overview of the fluorspar industry is provided. The U.S. had no reported mine production in 2000. Imports, sales from the U.S. National Defense Stockpile, and small amounts of synthetic fluorspar met domestic fluorspar needs. According to the U.S. Geographical Survey, 509 kt of fluorspar was consumed domestically.
