  159Antimony 
By Charlie Wyche 1 
 In 1972, domestic mine production of antimony, curtailed by a tragic fire
at the Sunshine Mine, declined to the lowest level in more than 30 years.
Secondary production also continued the downward trend from the 1969 high.
The 18% increase in consumption of primary antimony, however, was supplied
by a 75% increase in imports of ore, metal, and oxide. 
 The price of RMM brand antimony metal, in bulk, f.o.b. Laredo, Tex., was
stable at 57 cents per pound throughout the year. The free world antimony
price edged upward following buying interest from both consumers and dealers,
and the People's Republic of China's reluctance to sell. The quoted price
range of European lump ore, 60% antimony, declined during the first half
of 1972 but reversed the trend in the second half and showed substantial
strength at yearend. 
 Legislation and Government Programs.— Effective January 1, 1972, the
General Modification of Tariff Schedules of the United States, Federal Register
document 67—14749, filed on December 18, 1967 (Federal Regis- 
ter, v. 32, No. 244, Dec. 19, 1967, pp., 19002— 19004, reduced the
import duty on antimony metal TSUS No. 632.02 from 12 to 
1.0 cents per pound. No further reduction 
is scheduled. 
 Under authorization of Public Law 92— 105, enacted August 11, 19-71,
the -General Services Administration (GSA) disposed of 70 tons of antimony
from the Government stockpile in 1972. The total quantity authorized for
disposal is 6,000 tons of "C" and "D" grades metal with a maximum of 800
tons to be sold each calendar quarter. All of the antimony was restricted
to domestic consumption. Sales of the metal were in the form of granules,
pigs, siabs~ cakes, ingots, and broken pieces. All sales were made on an
"as-is" basis and in keeping with its policy in stockpile sales, no warranties
were made by GSA as to the chemical analysis, physical condition, or fitness
for any use or purpose of the metal. Total Government inventory at the close
of the year was 46,676 tons, of which 5,976 tons were surplus.
