    PROCESS OPTIMISATION OF MIXED COPPER ORES

    PROCESS OPTIMISATION OF MIXED COPPER ORES

    ores are either treated through standard sulphide flotation, sulphidisation or flotation followed by acid leaching. The performance of each of these process routes depends on the degree of oxidation as predicted by the proportion of acid soluble copper present in the ore. Process parameters must be aligned to optimize the recovery and grade
