  • Sequential Selective Flotation Process Flowsheet

    2020-6-25  A selective or sequential flotation flowsheet of two or more products. By utilizing selective flotation, two or more minerals in an ore are separated into individual high grade products. ORE TREATED: The most common of ores treated in this manner are lead zinc, copper-zinc-iron, copper-nickel, but application may be made to other two or three mineral separations. This flowsheet, without

  • Selective Flotation - Mineral Processing Metallurgy

    2020-6-25  Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the lab. In selective flotation, less is more! Over 2 years ago I wrote about ...

  • The selective flotation of pentlandite from a nickel ore ...

    1995-6-1  Bulk flotation An efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. This is the method which has been used for the flotation of nickel ores in industry and which we have termed the "standard bulk float". A selection of results for this ore is given in Table 3.
