Extracting Metals From Sulfide Ores

Extracting Metals From Sulfide Ores

Biochemical oxidation of the sulfide minerals releases the gold and allows it to be leached by the chemicals used in conventional gold leaching. Biochemical processes are being developed for the treatment of copper, nickel and cobalt sulfide ores and are expected to become the major method for recovery of these metals in the future.

Sulphide Gold Ore Treatment By Leaching And Flotation …

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 all the ore will report very low gold content in the tailings particularly on an ...

Recovery Of Gold In Pyritic Sulfide Ores

Recovery Of Gold In Pyritic Sulfide Ores

Recovery of gold in sulfide ores has fallen into several categories. First is froth flotation, and second is cyanidation of the ores. Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key ...
