froth flotation of gold ore

4 Types of Gold Ore Froth Flotation Combined Process

2019-11-11  For vein gold ore with high arsenic and sulfur or high carbon argillaceous, the gold sulfide concentrate can be obtained by the froth flotation, and then the flotation concentrate can be recovered by the thiourea leaching process. Thiourea gold extraction is a kind of increasingly sophisticated gold extraction method with low toxicity.

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

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).

Flotation kinetics of a pyritic gold ore - ScienceDirect

2011-1-17  Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant ...
