sulphidation of copper oxide ores for flotation

  • copper oxide ore processing

    Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy

  • 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 profile.
