  • Copper-Nickel ores - Danafloat

    Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

    The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69 ...

  • Copper-Cobalt ores - Danafloat

    Copper is separated from the cobalt in the bulk concentrate by raising the pH up to at least 11 which depresses the cobalt minerals. Cobalt depression can be enhanced by small cyanide dosages. If the cobalt is found with chalcopyrite, bulk flotation can be carried out with xanthate at pH 10, and separation made at pH 4 with an amine and ...

    However, the poor nickel floatability into the bulk concentrate indicated that TBP can be an effective flotation reagent for differential flotation of Cu-Ni bearing concentrates to preferentially depress pentlandite. TBP is likely to play duel role in augmenting the copper recovery while depressing the nickel sulphide minerals.
