Stibnite - Wikipedia

Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. It is the most important source for the metalloid antimony. The name is from the Greek στίβι stibi through the Latin stibium as the old name for the mineral and the element antimony.

antimony is one of a few elements that expand as they freeze. Antimony is a poor conductor of electricity and heat, and can be toxic in some cases, but less so in solid form. More than 100 mineral species of antimony are known; however, it most commonly combines with sulfur to form antimony sulfide or "stibnite" (Sb 2S 3).

Antimony is produced from minerals. The most important mineral source of the metal is stibnite (antimony trisulfide), but it is also found in trace amounts in silver, copper and lead ores (EU-RAR 2008). Antimony trioxide is obtained by roasting stibnite ores (Sb 2 S 3) which are reported to contain 55% antimony (IARC 1989).
