Antimony Mining - Encyclopedia of Arkansas

Antimony (Sb) is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) 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 solidification. The metal's main use is to impart stiffness and hardness to lead alloys. Antimony ...

Antimony Ore | MSquare Mining

Antimony is a lustrous tin-white metal. Although it is usually described as a metal, it possesses mixed metallic and nonmetallic characteristics, and is more properly described as a semimetal or metalloid. The antimony ore found in our mine is Stibnite, which is a sulfide bearing ore and is concentrated using a froth flotation process.
