  • Froth Flotation and Gold ExtractionManhattan Gold Silver

    Jul 23, 2014Most methods of waterbased gold extraction are dependent on golds lack of buoyancy to work. However, froth flotation uses a different property of gold to separate it from ore. Froth flotation is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water.
