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

WORLD REVIEW 
 Canada.—Chromasco Corp. 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.
