Chat OnlineA plant is processing a copper ore which contains two Cu minerals such as bornite and chalcopyrite. Although these minerals are recovered to the concentrate they show different flotation behavior and eventually their recovery values different in all size ranges. Chalcopyrite showed better recovery values than bornite. It is also reported that Fes
