167Bauxite and Alumina By Horace F. Kurtz' World bauxite production rose 6% and reached a record high level of over 81 million long tons in 1977. Producers in Australia and Jamaica provided most of the increase over the previous year. The production of alumma (alummum oxide) the intermediate product between bauxite and aluminum metal, also was a new record, totaling over 32 million short tons in 1977. The increases in the output of bauxite and alumina largely reflected a continued growth in world demand for primary aluminum, the principal end use of these commodities. In the United States, bauxite production increased slightly to nearly 2 million long tons. Alumina production rose about 4% to 6.65 million short tons, while imports of alumina increased 14% to over 4 million tons. Imports provided about 88% of the bauxite used by domestic alumina producers and 38% of the new supply (production plus imports) of alumina. Legislation and Government Programs.—.The Federal Preparedness Agency, General Services Administration (GSA), stockpile inventories at the end of 1977 included about 14.2 million long tons of metal-grade bauxite (excluding excess that had been sold), 173,000 tons of calcined refractory-grade bauxite, and no alumina. Stockpile goals at yearend were 0.5 million long tons of metal-grade bauxite, 2.1 million tons of refractory-grade bauxite, and 11.5 million short tons of alumina.

Includes bauxite imported into the Virgin Islands. DOMESTIC PRODUCTION Bauxite production in the United States increased 1% to 1.98 million long tons (dry basis) in 1977. Output increased in all three producing States, Alabama, Arkansas, and Georgia. Arkansas again produced 85% of the total. All of the bauxite was mined at open pit operations, as the only underground mine active in recent years did not produce in 1977. In Arkansas, bauxite was mined by Aluminum Co. of America (Alcoa), American Cyanamid Co., and Reynolds Mining Corp. in Saline County, and by Reynolds in Pulaski County. American Cyanamid calcined bauxite at its plant at Benton, Ark., and Porocel Corp. (owned by Engelhard Minerals & Chemicals Corp.) produced activated bauxite at its Berger plant.
