Processing of Gold Bearing Antimony Ore: Mineral ...

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.
