ard Lime and Refractories Co.), and Northwest Magnesite Co. Total production
of refractory magnesia in 1972 was 575,707 tons. 
 During the year, 189, 889 tons of causticcalcined magnesia was produced
by Basic Inc., Basic Magnesia, Inc., The Dow Chemical Company, Kaiser Aluminum
& Chemical Corp., Martin-Marietta Chemicals, and Michigan Chemical Corp.
Six companies produced 11,091 tons of specified magnesias. 
 Magnesium chloride was produced by American Magnesium Co, J. T. Baker Chemical
Co., The Dow Chemical Co., FMC Corp., Great Salt Lake Minerals & Chemicals
Corp., Kaiser Aluminum & Chemical Corp., Mallinckrodt Chemical Works,
and NL Industries, Inc. Most of the magnesium chloride production was used
for magnesium metal cell feed. 
 Production of magnesium sulfate was reported by four companies. Producers
of other magnesium compounds were J. T. Baker Chemical Co., Mallinckrodt
Chemical Works, Merck & Co., Inc., and Waverly Chemical Co., Inc. 
 In 1972, 696,102 tons of magnesia was used in the production of basic refractories,
compared with 626,513 tons in 1971. Consumption of caustic-calcined magnesia
for uses other than the production of refractory magnesia included chemical
processing, animal feed, pulp and paper, rayon, and sugar. Specified magnesias
were used primarily in electrical, medicinal, and rubber applications. 
 Basic Magnesia, Inc., completed an expansion program at its sea water magnesia
plant in Port St. Joe, Fla., with the installation of special material processing
equipment, increased bagging capacity, and new bulk loading facilities for
both trucks and railroad cars. Improvements were also made in the reaction
system controls, which were designed to yield more uniform and higher quality
oxides.

 Domestic producers of magnesium compounds by raw material source, location,
and annual capacity are listed as follows: 
 Olivine was consumed as a molding sand in various foundries and as a metallurgical
flux in the smelting of steel. 
 Magnesium chloride was used as an antifreeze agent and in the processing
of molasses. Magnesium carbonate was consumed in the production of cosmetics
and pharmaceuticals.
