Froth Flotation and Gold Extraction

Jul 23, 2014· Most methods of water-based 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).

Gold

Flotation is the most common and effective way of golden separation, because you can extract the free gold and splices of gold Floatability of gold depends on the nature of gold, size of fine particles of gold, shape of gold particles, chemical purity of gold, presence of impurities, composition of the films on the surface of golden particles.
