1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, …
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).
