Froth Flotation and Gold Extraction Manhattan Gold & Silver
Jul 23, 2014 · Most methods of waterbased gold extraction are dependent on gold''s 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).
