Abstract
The flotation of four copper sulfide minerals (chalcopyrite, chalcocite, bornite, covellite) and pyrite with xanthates shows that a minimum in the collector concentration necessary for flotation usually occurs at about C-5 (amyl) to C-8 (octyl) for the straight chain xanthates. Comparison of straight-chain and branched-chain compounds demonstrated that while short, branched chain xanthates out perform their straight chain analogs, above ∼ C-5 the branched-chain xanthates are less effective as compared to the straight chain form. When Cu 2+ is added to the flotation system, it was found that a minimal amount will often produce an enhanced flotation recovery, while greater amounts will either produce essentially no effect or may cause a slight decrease in flotation.
