Froth Flotation and Gold Extraction
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).
