Sulphide Gold Ore Treatment by Leaching and Flotation Process A Flowsheet to recovery gold from sulfide ores. There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used. In Gold
Recovery of Gold in Pyritic Sulfide Ores The now extinct Us Bureau of Mines conducted numerous studies of gold in pyrite, and sulfide ores over the years, until their untimely demise in the 1990's.
Generally, recovery of the gold from the sulfide concentrates requires further processing, usually by roasting or wet pressure oxidation. These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for final recovery of the gold.
