  • Froth Flotation and Gold Extraction Manhattan Gold Silver

    Jul 23, 2014· Most methods ofwater-based gold extraction are dependent on gold’s lack of buoyancy to work. However, frothflotationuses a different property of gold to separate it from ore. Frothflotationis a method for separating hydrophobic materials (which will not mix withwater) from hydrophilic materials (which readily mix withwater).
