Froth flotation is a highly versatile method for physically separating particles based reported by many investigators to depress pyrite flotation, and yet none of
Gold extraction refers to the processes required to extract gold from its ores. This may require a However, froth flotation processes may also be used to concentrate the gold. associated with sulfide minerals such as pyrite, chalcopyrite or arsenopyrite, and when such sulfides are present in large quantities in the ore.
gold contained in pyrite ranges from 0.01 to 0.07 m gold-bearing ores, the flotation technique is used, not treatment, but also for beneficiation and separation.
