Extraction of Gold by Flotation Process

Gold is an easy-floating mineral, so extraction of gold by flotation process has always been one of the effective ways to process gold-bearing ores. In primary gold deposits, gold minerals often coexist with sulfide minerals such as pyrite, chalcopyrite, galena, and sphalerite. These minerals are both easy-floating minerals and form stable mineralized foams. They are the ideal carrier minerals ...
