Rcovery of gold in pyritic ores Mine Engineer.Com

Recovery of Gold in Pyritic Sulfide Ores In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite

How to Separate Gold from Pyrite

In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

Gold-Pyrite ores

Consequently, gold flotation recovery requires a focus on floating the associated base metals (predominantly lead, copper) and often pyrite minerals. While lime is often used in base sulphide mineral flotation, because excess lime also tends to depress gold flotation, a balance must be maintained between good base metal metallurgy and gold
