ABSTRACT:
The present invention involves a method for separating copper sulfide from rimmed iron sulfide by flotation. Prior to flotation, a slurry containing the sulfides is oxidized and conditioned to achieve a pH greater than pH 9. Thereafter, the slurry is subjected to a froth floatation process by which a copper sulfide, such as chalcopyrite, concentrate is recovered.
