Metallurgy | The Canadian Encyclopedia

2006-2-7 · Metallurgy is the art, science and technology of turning metals and alloys (i.e., materials consisting of two or more metals) into forms suitable for practical use. Metals make up a large portion of the Earth''s crust (courtesy Alcan Aluminum Ltd). Electrolysis is the key process in refining many metals.

Metallurgy

Flotation of Gold and Gold-Bearing Ores

2016-1-1 · 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).
