Flotation of Gold and Gold-Bearing Ores - ScienceDirect

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, 1939, Richards and Locke, 1940, Taggart, 1945)...
