Chat Online· Richardson and Walker (1985) showed that the flotation of chalcocite bornite chalcopyrite and pyrite with potassium ethyl xanthate is controlled by the conditioning redox potential (Eh). The active surface entities were found to be metal xanthates for chalcocite and bornite dixanthogen for pyrite metal xanthate for initial flotation of chalcopyrite and dixanthogen for full flotation.
Chat Online· The flotation behaviour of chalcopyrite was best described by the Dose-Response function (Eq. ) which was adopted to determine its critical degree of surface oxidation.
