Flotation of Gold and Gold Bearing Ores ScienceDirect

Flotation of Gold and Gold Bearing Ores ScienceDirect

Jan 01, 2016 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).

Extract copper and gold from low grade ores FLSmidth

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the world’s current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation.
