    Copper Flotation Mineral Processing & Metallurgy

    Porphyry copper ores, usually medium to medium hard, require grinding to about 65 mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65 mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.
