flotation for copper gold

Copper Mining and Processing: Processing of Copper Ores ...Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, .Sulphide Flotation - an overview | ScienceDirect TopicsMany copper–gold concentrators have a combination of flash flotation and gravity separation in the milling circuit to enhance overall free gold recovery. The reason for the inclusion of gravity separation at these concentrators is that the coarse free gold is not recovered effectively in the flash flotation cell.
