Main Copper Sulphide Extraction Process
Generally, the common copper sulfide minerals mainly include chalcocite, covellite, bornite, copper pyrites and tennantite, and their inherent floatability decrease in turn. Copper sulfide ore has better floatability than sphalerite, pyrite and another sulphide, so it is more likely to float from the pulp by adsorpting collector.
