The country that leads in the manufacture of chromium products, such
as ferrochrome and chrome chemicals, is the United States. In normal
times the United States consumes more than one-third of the annual
consumption of chromite by the world. In 1913 the chromite used by
manufacturers of ferrochrome and chrome chemicals in the United States
amounted to 65,000 tons. Owing to the war, the consumption increased
markedly until 1917, when it was nearly 130,000 tons. The normal
consumption of chromite in England is about 25,000 tons and in France
approximately 35,000 tons. These amounts have not greatly increased in
recent years. Germany is an important producer of chromium products,
normally consuming 30,000 tons of chromite annually. Russia and the
former Austrian Empire used perhaps 5,000 tons each annually. Norway
and Sweden use small amounts. Russia’s consumption has been mainly in
the manufacture of chromium chemicals, and that of the former Austrian
Empire was principally for refractory purposes. In Norway and Sweden
small amounts of ferrochrome are produced.
=United States.=--The United States, although the world’s largest
consumer of chromite, is not an important producer of this mineral
in normal times. During the 30 years preceding the war, the annual
production never exceeded 4,000 long tons of crude ore, and during the
last 15 years preceding the war the largest annual production was 598
long tons, in 1909. The production in 1913 was less than 1 per cent. of
the domestic requirements.
The chromite supply of the United States has, therefore, come largely
from foreign sources, and these sources have been mainly Asia Minor,
Rhodesia, and New Caledonia. Before 1905 Turkey in Asia was the
principal source of supply. Since then, however, Rhodesia and New
Caledonia have largely replaced Turkey in the American chrome market.
Although numerous deposits of chromite occur in the western United
States and locally in the eastern states, these deposits are usually
small and scattered or of low grade. On account of their physical
character, small size, scattered occurrence, or distance from consuming
centers, domestic chromite could not be furnished to consumers in
the required grade or for the price that chromite from rich foreign
deposits could be furnished. For this reason the American chromite
deposits remained undeveloped and no ore was mined except small
quantities which were consumed for refractory purposes in neighboring
metallurgical works.
