236 MINERALS YEARBOOK, 1972 PRICES AND SPECIFICATIONS Prices for calcium metal ranged from $1 to $5 per pound. Calcium chloride is usually sold either as solid flake or pellet averaging about 75% CaCl2 or as a concentrated liquid averaging about 40% CaCl2. FOREIGN TRADE Exports of calcium chloride, mainly to Canada, Mexico, the United Kingdom, Venezuela, and Sweden, were 18,750 tons valued at $868,400. Exports of dicalcium phosphate, mainly to Mexico, Canada, Brazil, Taiwan, and Thailand, were 19,710 tons valued at $3,277,000. Exports of precipitated calcium carbonate, mainly to Mexico, Canada, Venezuela, South Vietnam, and Honduras, were 8,940 tons valued at $823,000. Total imports of calcium and calcium compounds were 137,200 tons valued at $7,291,000. Imports of calcium metal from Ontario were 124 tons valued at $181,400. Imports of calcium chloride, mainly from Canada and Belgium, were 6,128 tons valued at $225,500, a decrease of 53% from those of 1971. Imports of other calcium compounds, mainly from Norway, Turkey, Belgium, France, and Canada, were 131,000 tons valued at $6,884,000. Imports of other calcium compounds included 46,810 tons of calcium nitrate from Norway, Trinidad, Sweden, and West Germany; 20,780 tons of whiting from France, the United Kingdom, Switzerland, and Belgium; 20,230 tons of calcium borate from Turkey; 19,580 tons of dicalcium phosphate from Belgium, Canada, West Germany, and Japan; 11,110 tons of calcium carbide from Canada; 3,165 tons of calcium Table 2.—U.S. imports for consumption of calcium and calcium chloride Year Calcium - Pounds Value Calcium chloride Short tons Value 1968 1969 1970 1971 1972 137,251 662,200 164,769 48,391 248,080 $120,416 619,000 141,125 29,751 181,437 14,069 9,226 8,280 13,019 6,128 $522,680 349,998 359,096 543,656 225,463 cyanamide from Canada, Norway, West Germany, and Belgium; 2,467 tons of calcium cyanide from Canada and Japan; 1,895 tons of precipitated calcium carbonate from United Kingdom, Japan, and West Germany; 999 tons of calcium hypochlorite from Japan; 327 tons of chlorinated lime from the United Kingdom and West Germany; and 3,637 tons of miscellaneous calcium compounds.

Ltd., produced calcium metal at its Haley, Ontario, smelter. Canada continued to lead all other countries in the production of calcium metal; output in 1971 was 304,000 pounds valued at $282,000. Canada was the leading source of U.S. imports of calcium chloride. France.—Planet-Wattohm S.A., a subsidiary of Compagnie de Mokta, produced calcium metal by the Pidgeon process.
