Gold Leaching Plant Flowsheets – Gold Metallurgy

The Kalgoorlie ore deposits occur in Pre-Cambrian rocks and essentially consist of calc schist and quartz-dolerite-greenstone. The ores contain free gold and tellurides. Auriferrous pyrite is the most abundant sulphide and is occasionally associated with chalcopyrite, tetrahedrite and arseno-pyrite. The gold associated with the pyrite is in a very fine state and is not liberated…

Rcovery of gold in pyritic ores - Mine Engineer.Com

Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to ...
