Flotation of gold and gold-bearing ores
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, 1939; Richards and Locke, 1940; Taggart, 1945).

Wetting and not wetting or water-absorbing is the principle of flotation. Some minerals are wetted, whereas others are not wetted. Wetting is a variable property of minerals and depends upon the surface properties of the solid, liquid, and gaseous conditions. Minerals that are wetted do not float, whereas those which are not wetted float well.
