Froth Flotation and Gold Extraction - Manhattan Gold & Silver

Most methods of water-based 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).
