6-Characterization of the Gold Ore to Acquire an

2017-9-28  The mineralization of ore found in the research area is sulfide minerals i.e. pyrite, chalcopyrite, sphalerite, galena and arsenopyrite. In general, gold ore processing in small-scale mining uses an amalgamator, and is less precise in the gold ore preparation stage. Research on the degrees of gold mineral liberation through the milling process stage is necessary. The objectives of this study were: (a) analyzing the geological characterization of gold ore

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
