shifts in prices of antimony and of replacing
metals there is a corresponding shift in use
SECONDARY SOURCES AND RECOVERY
Over 50 percent of the annual domestic sup-
ply of antimony is derived from scrap. Sec-
ondary antimony recovered at 194 plants in
1957 totaled 22,600 short tons valued at $15.8
million. Recovery of antimony from battery-
plate scrap comprised 60 percent of the total
secondary output. Type-metal scrap yielded
3,200 tons of antimony. Bearing-metal scrap
contributed most of the remaining feed mate-
rial. All secondary antimony was recovered as
regenerated antimonial alloys.
The United States has a large quantity of
antimonial alloys now in use that will event-
ually return as scrap to be reprocessed. Con-
sideration of the number of automobiles in use
leads to a conservative estimate of 150,000 tons
of recoverable antimony available from this
RESERVES AND RESOURCES
There are no currently commercial antimony
deposits in the United States. However, ore
reserves of some other metals are a measure of
the quantity of byproduct antimony that will
be recovered at lead smelters. The Geological
Survey (10)2 estimates this category of re-
sources to be 50,000 tons of recoverable anti-
mony. Submarginal material that could be
economically mined largely or entirely for an-
timony at prices of 40 to 60 cents per pound
contain about 50,000 short tons of metal (10).
Half of this quantity is in the Yellow Pine dis-
trict, Idaho. The Geological Survey estimates
that at prices between 60 cents and $1.50 per
pound marginal portions of known mineralized
districts and new discoveries would yield an
additional 100,000 tons.
There are few deposits of antimony in which
ore is developed in advance of current mining
requirements. World resources, therefore, are
necessarily based largely on known correlative
data such as historical production levels and
geologic patterns of occurrence.
China is the dominant possessor of reserves.
Estimates range from 2 to 5.7 million tons of
contained antimony-a quantity that dwarfs
the reserve of any other country. Bolivia is
second to China with an estimated 400,000 tons.
Mexico, the Union of South Africa, and
U.S.S.R. are estimated to have approximately
the same level of reserves-each is assigned
250,000 tons of contained antimony. Yugo-

slavia, Australia, and Algeria-Morocco each
has approximately 100,000 tons. Collectively,
Canada, Peru, Turkey, and Czechoslovakia
have 225,000 tons. An additional reserve in
many known small deposits throughout Aus-
tria, Hungary, France, and Japan contains
about 175,000 tons of antimony. Therefore,
the world reserve, excluding China, is esti-
mated as approximately 2 million tons.
CONSERVATION PRACTICES IN PRODUC-
TION AND USES
The high volatilization losses attending ore
smelting are for the most part compensated by
recirculating the entrapped flue dusts.
Lead smelters recover antimony metal, oxide,
and antimonial lead from intermediate smelter
products, such as slags, drosses, flue dusts, and
residues generated at copper, lead, tin, and
Users of antimonial alloys, such as battery,
bearing, and type-metal manufacturers recir-
culate new and used scrap metal. Primary re-
fineries use varying amounts of scrap in addi-
tion to ores, concentrates, and intermediate
SOURCES OF STATISTICAL INFORMATION
Data on production, consumption, and stocks
of primary antimony are collected and tabu-
lated quarterly by the Bureau of Mines. The
Department of State through its Foreign Serv-
ice reports furnishes statistics relating to the
antimony industry in foreign countries. There
are numerous foreign publications that give
fragmental statistics on foreign production and
consumption. Import and export statistics are
obtained from Department of Commerce,
Bureau of the Census.
PRODUCTION, CONSUMPTION, AND FOR-
World production of primary antimony is
approximately 55,000 tons annually. Yearly
smelter production in the United States is
about 35,000 tons, including 23,000 tons of anti-
mony in alloys generated from scrap. Of the
12,000 tons of primary smelter output, approx-
imately 65 percent comes from imported ores
and concentrates and 35 percent from byprod-
uct materials segregated in refining lead bul-
lion and other intermediate metallurgical prod-
ucts. These byproducts, in turn, are derived
from both foreign and domestic ores.
The United States requires 20 to 30 percent
of the world's primary output. Other principal
consuming countries are United Kingdom,
U.S.S.R., France, Belgium, Japan, West Ger-
many, and Italy.
