 MINERALS YEARBOOK, 1972 Figure l.—Prindpal sources of bauxite for
alumina plants in the United Statesand the Virgin Islands in 1972.192 
Guyana. The use of bauxite for the manufacture of refractories has increased
every year but one since 1958 when consumption was 60,000 tons. 
 The use of bauxite to make artificial abrasives also increased in 1972 to
about the average level of the past decade. All of the bauxite used by the
abrasives industry was caicined. Most of the ore came from Sunnam, and the
remainder came from Australia and Guyana. Data on consumption by the abrasives
industry included bauxite fused and crushed in Canada since much of this
material is made into abrasive wheels and coated products in the United States.
 Chemical producers decreased their consumption of bauxite by 11% during
the year. Other consumers of bauxite, in descending order of magnitude, included
the cement, oil and gas, and steel and ferroalloys industries, and municipal
waterworks.

 Calcined alumina consumed by the 30 primary aluminum plants in the United
States totaled 7.94 million short tons, an increase of 5.6%. Alumina consumption
data for other uses were not available. A significant quantity was used to
make aluminum fluoride and synthetic cryolite, which is also used in the
production of primary aluminum.
