copper and molybdenum flotation

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description.Molybdenum will float naturally with the copperbut can be crowded in the froth by the copper mineralization and use of amolycollector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability

    copper molybdenum ore beneficiation,flotation separation

    It should be pointed out that because of the relatively low grade ofmolybdenumore, its output is a mixture ofcopper and molybdenum.It is presented in the form of concentrate, which is then systematically separated fromcopper and molybdenumto obtainmolybdenumconcentrate andcopperconcentrate. In theflotationofcopper-molybdenumore, two more aspects of beneficiation operations were implemented. After the operation is completed,molybdenum…

    molybdenite flotationfromcopper molybdenumconcentrates

    Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite …
