闪锌矿

Flotation of the three pure sulfide minerals (named amesonite, marmatite and pyrrhppite) used different regeants, is discussed as to know how the useful part is separated from the ore. The flotation behavior of the three minerals is that in low pH value they have good buoyancy,while in high pH value they have bad buoyancy.
