Antimony Mineral Processing . Process Introduction Proportion of antimony ore is far greater than proportion of gangue, so it will be separated by using the method gravity method has many features, high efficiency, energy saving, and environment protection, which can make the lowgrade ore enrichment advance.

Antimony (Sb) is a hard, brittle, silverwhite metal with a relatively high specific gravity () and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidifiion. The metal's main use is to impart stiffness and hardness to lead alloys. Antimony ...

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.
