Porphyry copper ores usuallymediumtomedium hard require grinding to about 65 mesh to economically liberate thecopper mineralsfrom the gangue Although a clean rougher tailing can often be achieved at 65 mesh thecopper mineralis not liberatedsufficientlyto make ahigh grade copperconcentrate thus some form of regrinding is necessary on the rougherflotation copperconcentrate.
The copper content of the solution varies from less than 1 gL to several grams per liter Other leaching methods include ammonia leaching which is used for certain copper oxide ores These methods are called leach precipitation flotation and are applied to mixed sulfide ores.
Abstract Sulphidising flotation of oxide coppercobalt ores with sodium hydrosulphide used as sulphidising agent is common practice in Katanga Democratic Republic of Congo From laboratory investigations sodium hydrosulphide proved to enhance flotation selectivity of copper and cobalt towards the gangue minerals while ammonium sulphide emerged as a strong non selective sulphidiser.
