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

Chat Online· In this paper the effect of sodium butyl xanthate (NaBX) adsorption on the surface of bornite at different pH on flotation was studied by adsorption kinetic and thermodynamic. The flotation results demonstrated that the recovery was the highest when pH was 9 in NaBX solution (4 10−5 mol/L). The adsorption kinetics showed the reaction of NaBX on the bornite conformed to the second order
