    Separating Minerals by Floatation ABB

    Copper processing example A high pH is important in the processing of copper ore to maximize this minerals floatation properties. Most copper ore slurries tend to be acidic. Plants typically add lime to the slurry in the mill or floatation circuit increasing its alkalinity. A typical copper operation contains many floatation cells often

    GROWING ROLE OF SOLVENT EXTRACTION IN COPPER

    mixtures of extractants were used for example Cognis reagent LIX 64N blend of LIX 64 and LIX 63. LIX 64 alone was able to extract copper selectively from iron in the pH range 1.5-2.5 but with the disadvantage of slow rate of extraction. This was solved by the addition of a small amount of LIX 63. The mixture LIX64N for many

    Copper Sulfide an overview ScienceDirect Topics

    All copper sulfides require the presence of Fe 3 and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3.The resulting Fe 2 is reoxidized to Fe 3 by O 2.The FeIIFeIII redox couple acts in a catalytic manner in these reactions shown for elevated-temperature reaction conditions where the sulfur-containing product is sulfate rather than the elemental .
