Copper Mining and Processing Processing of Copper Ores

B. Processing of Sulfide Ore. Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps 1) froth flotation, 2) thickening, 3) smelting, and 4) electrolysis.

Recovery of Gold in Pyritic Sulfide Ores Mine Engineer.Com

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.

Why is the froth flotation method only used for sulphide ores?

Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. This method is also used in waste recyling and paper industries.. this method also seperates hydrophobic substances from hydrophilic substances..
