Processing of Gold Bearing Antimony Ore
A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold.
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 …
