Bauxite and Alumina 
By Luke H. 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
