Aug 02, 2020· Advancing flotation process technologies to maximize gold extraction. The process used to extract gold is largely dependent upon the ore deposit and the mineralogy of the ore.

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.
