' Capacity may vary depending upon the bauxite used. 
 The production of alumina and aluminum oxide products at the eight alumina
plants in the continental United States and the plant in the Virgin Islands
totaled 6.98 million short tons in 1972, a decline of 
3%. The total production included 6.23 million tons of calcined alumina,
671,000 tons of commercial alumina trihydrate, and 70,000 tons of tabular,
activated, and other alumina. The production of commercial alumina trihydrate
increased 12% and 
reached a level more than double the output in 1968. 
 Shipments of alumina were 6.97 million tons, valued at $497 million. Approximately
6.02 million tons were shipped to primary aluminum plants. The chemical indisstry,
including the producers of aluminum fluoride fluxes for aluminum plants,
received the second largest tonnage, and most of the rest of the alumina
was shipped to producers of abrasives, ceramics, and refractories.

CONSUMPTION AND USES 
 The consumption of bauxite in the United States (inc'uding the Virgin Islands)
in 1972 decreased 2% to 15.4 million long tons (dry basis). Most of the decline
resulted from lower production of calcined alumina for the aluminum industry.
About 87% of the bauxite consumed was imported ore. 
 The production of alumina and related products accounted ' for 93% of the
total bauxite consumption. An average of 2.13 long dry tons of bauxite was
used to produce 1 short ton (calcined basis) of alumina. The two alumina
plants in Arkansas were based mainly on the use of domestic bauxite, and
the other seven alumina plants used only imported ore. 
 Bauxite consumption by the refractories industry reached a record high level
of over 400,000 long tons (dry basis). Nearly all of this bauxite was used
in the calcined form, and 82% was imported, mainly from
