Gold Ore Flotation Concentrate

Beneficiation of the gold bearing ore by gravity and flotation

Gold concentration usually consists of gravity separation flotation cyanidation or the combination of these processes The choice among these processes depends on the mineralogical characterization and gold content of the ore Recently the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations
