Sulphide Gold Ore Treatment by Leaching and Flotation Process
Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of ... Gold Ore …
Roasting and Refractory Gold Ore
During roasting, refractory gold ore is treated with extremely hot air. This causes the sulfites to oxidize, separate from the ore, and become sulfur dioxide. Once all of the sulfides are oxidized, the remaining gold ore can be processed normally. The roasting method has been around for hundreds of years. Prior to the 20th century, the process ...
Gold Sulphide Ore Oxidation by Alkaline Pressure
Cyanide consumption was 0.25 kg NaCN per metric ton of ore. A flowsheet for treating sulfidic low-grade gold ore is proposed.
