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 ...

What is Sulfide Mining? | Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.

The native elements contain the most gold, followed by the sulfide minerals. Several gold tellurides are known, but no gold selenides have been reported, and only one sulfide, the telluride-sulfide mineral nagyagite, ii:; known. The nonmetallic minerals carry the least gold, and the light-colored minerals generally contain less gold

Dissolving Ore? - Gold Prospectors Association of America ...

15-10-2016· When gold is locked up as a sulfide, even the cyanide leaching doesn't work to loosen the gold....it needs to be oxidized first. usually by roasting it under intense heat. If you are describing the fact that you may have free mill gold, using the HCl with bleach will likely dissolve the gold and allow you to purify it. But....if you do have free mill gold wouldnt that be the same as flour gold?
