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.

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.
