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 chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature.

Metallurgy. 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.
