  • Molybdenite Flotation From Coppermolybdenum

    Molybdenite Flotation From Coppermolybdenum

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