sulfide gold ore refiners


In general, such methods were applied at gold refineries on a low scale due to their cumbersomeness and complexity. Acid leaching of impurities from the gold-bearing cathode deposit is one of the promising areas of enhancing the quality of gold ingots.

Froth flotation is usually applied when the gold present in an ore is closely associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore. In this case, concentration of the sulfides results in concentration of gold values.

A geologist said that the fire assay may not have extracted the gold from the ore, because of the various gold-silver-copper sulfur refractory compounds within due to a limited process that was used. This type of ore requires more extensive process steps to reduce the gold. We have tried various different methods of recovery, without success.

You have to separate the gold from the ore, this is usually done by using cyanide to dissolve the gold. If you are good with a table then you should be able to get a concentrate which can be treated with aqua regia to dissolve the gold. You only use aqua regia to treat concentrates if you cannot get cyanide, the costs are a lot higher.
