mining chalcopyrite copper

A Review on Novel Techniques for Chalcopyrite Ore

2012-1-1  The first step in the chalcopyrite processing is to liberate the copper minerals and remove waste constituents such as alumina, limestone, pyrite and silica so that the copper and non-ferrous mineral values are concentrated into a product containing between 20 to 30 percent copper.
