Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide …

The process and methods of antimony ore gravity separation are briefly introduced. The particle size of antimony ores is generally coarse, and the specific gravity of antimony crystals is much greater than that of associated gangue. Therefore, it is an ideal method to use gravity separation to treat antimony ores.

Beneficiation of Antimony Oxide Ore: A Review
Natural antimony was first discovered in 1777 by the Germans. By the 18th century, antimony was being roasted to reduce it to metal. In this process, stibnite was calcined to form an oxide, then reacted with carbon to liberate metal antimony, as follows: 2Sb2S3 + 9O2 2Sb2O3 + 6SO2↑. Sb2O 3 + 3C 2Sb + 3CO. ↑.

Antimony Mobilization through Two Contrasting Gold Ore Processing
Antimony, a toxic metalloid similar to arsenic, is present at variable levels in most gold-bearing rocks. Antimony is soluble in the surface environment, so antimony (Sb) mobilization in mine waters is an environmental issue around gold mines. The Reefton gold mine was originally developed in gold-bearing quartz veins; Sb concentrations were …
