    Flotation Circuit - an overview ScienceDirect Topics

    The example of flotation circuit without grinding considered the concentration of copper ore. The feed to the circuit corresponded to 6 t/h of chalcopyrite (33% of copper), 12 t/h of chalcopyrite slow (16% of copper), and 300 t/h of gangue. The superstructure considers five flotation stages. If all interconnection was allowed, there were over 3 ...
