A wet chemical process was developed for the separation of gold from goldbearing 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.
Ore of sufficient yield is very rare. Gold's Extraction and Purifiion# Because of gold's inertness some 80% of gold within ore is in its elemental state. There are several processes for extracting, and then purifying it. Amalgamation is a mercury based process which works because of gold's willingness to be dissolved by mercury.
