Baumgardner' and Ruth A. Hough2 A sharp decline in bauxite production in 1978 in Australia the leading world suppli er was only partially offset by increases in Gumea and Jamaica and total world mine output was lower than in 1977. Production increased markedly m 1979 to a new world record World production of alumina in 1978 was slightly higher than in 1977 and also increased in 1979 Domestic production of bauxite and alumina m 1978 79 as in past years showed little change Jamaica Guinea and Suriname remain ed the principal sources of bauxite imported irito the United States in 1978-79. Brazil became a new supplier of bauxite to the United States in the fourth quarter of 1979. Also during 1979; a decline in imports of cálcinedrefractory~grade bauxite from Guyana caused some concern among domestic consumers. Australia, Jamaica, and Sunname were the principal suppliers of alumina imported by theUnited States. Note All quantities in this chapter are given in metric tons unless otherwise indicated. Metric tons can be converted to long tons by multiplying by 0.984207 or to short tons by multiplying by 1.10231. Legislation and Government Programs.—General Services Administration stockpiles of bauxite remained virtually unchanged throughout 1978-79, except for the shipment in 1978 of metal-grade bauxite which had been sold previously. Inventories at the end of 1979 included about 14.4 million metric tons of metal-grade bauxite, and 177,000 tons of calcined refractorygrade bauxite. Stockpile goals were 0.5 million tons of metal-grade bauxite, 2.1 million tons of refractory-grade bauxite, and 10.5 million tons of alumina. There were no Government stocks of alumina. The Tokyo Round of international trade negotiations, which resulted in agreements to reduce certain tariffs, did not affect the duties on U.S. imports of bauxite and alumina which have been suspended since 1971. 1Excludes calcined bauxite. Includes bauxite imported into the Virgin Islands. DOMESTIC PRODUCTION Bauxite mines were operated in Arkansas has been from open pit mines since Rey in 1978-79 by the Aluminum Co. of America nolds closed the last domestic underground (Alcoa), American Cyanamid Co., and Hey- bauxite mine in 1976. In both 1978 and 1979 nolds Mining Corp. in Saline County and by American Cyanamid produced calcined Reynolds in Pulaski County. All production bauxite at its Benton plant, and Porocel 95.
