The process mineralogy of gold: The classification of

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important.

The most efficient gold extraction processing route is directly related to the inherent mineralogical features of the gold ore being processed. The mineral assemblage determines the performance of all chemical and physical processes involved in gold extraction (e.g. Chryssoulis and Cabri, 1990; Marsden and House, 1992; Chryssoulis

Gold Process Mineralogy SGS

Antimony, bismuth sulfide, and telluride gold ores are often somewhat refractory due to the presence of slow-dissolving gold minerals such as aurostibite (AuSb2), maldonite (Au2Bi), and gold tellurides. Carbonaceous sulfide ores are the typical refractory ores because the gold is fine-grained, and usually, is predominantly associated with the sulfide minerals (pyrite and arsenopyrite) that are present in carbonaceous ores. Gold in carbonaceous sulfide ores is usually recovered by pre-oxidation followed by cyanidation with or without prior concentration by flotation. Gold recovery from the carbonaceous sulfide ore is more difficult not only because the gold is fine-grained and locked in sulfide minerals but also because the gold can be robbed from the cyanide solution by the carbonaceous matter.3 At Barrick’s Goldstrike Mine, where gold occurs in pyrite in refractory sulfide ore and double-refractory sulfide/carbonaceous ore, gold ores
