what is differential flotation process for nickel and sulfur

A sequential flotation process for the recovery of highgrade concentrates of copper, lead and cobaltnickel from sulfide ores is provided. A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration, and the conditioned pulp subjected to sequential flotation, with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper.

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