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 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...
How to build a mine – Resource World Magazine
Gold and silver can be recovered by gravity for the free gold/silver followed by cyanidation of the lower grade ore to make doré bars on site from both products. Alternatively, after gravity, a flotation step can be used to produce a lower grade concentrate to be shipped to smelters worldwide for final processing.
