  • 4 Types of Gold Ore Froth Flotation Combined Process

    For vein gold ore with high arsenic and sulfur or high carbon argillaceous the gold sulfide concentrate can be obtained by the froth flotation and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity.

    Froth flotation is the use of the physical and chemical properties of the surface of the ore the use of chemical separation of useful ore. In the process of froth flotation useful minerals are separated by floating them in the foams and the way of keeping gangue minerals in the pulp is called positive flotation while the way of floating gangue minerals in the foam is called reverse flotation.>
