Jul 22, 2021· Production of antimony became critical during World War II, when it was used for batteries, flame retardant and weapons. "It was a huge boon to the World War II efforts," said ia Gillerman, a research geologist with the Idaho Geological Survey. "It was crucial." Mining in the Stibnite District expanded throughout the war.

The Stibnite mining area (study area) is in Boise and Payette National Forests, 14 miles southeast of Yellow Pine, Idaho (fig. 1). The area was intermittently mined for gold, silver, mercury, antimony, arsenic, and tungsten from 1919 to 1997. During World War II, the Stibnite mining area produced
LIQUATION: Liquation is the melting of stibnite into "crudum" or "needle antimony". It is carried out between 550 and 600 degrees C. If the temperature is lower, the recovery is poor. If the temperature is any higher, the stibnite volatilizes into oxide. This method is used to upgrade low-grade ores. The ore is placed on … Metallurgy Read More »
Antimony (Sb; CASRN 7440-36-0) is a semimetal element with chemical properties similar to lead, arsenic, and bismuth. In nature, it is found associated with sulfur as stibnite. Antimony is used in white metal, a group of alloys having relatively low melting points. White metal usually contains tin, lead, or antimony as the chief component.
