A New Application For Flotation Of Oxidized Copper Ore

2016-8-29  When flotation of the oxidized copper ore was performed under standard operating conditions in the plant, good results were not obtained. Because of this, the flotation of samples obtained from sulfurized medium containing different ratios of H2S+ H2O gases was done under the same conditions. Following flotation, it was seen that copper, cobalt and sulfur present in the medium were concentrated. In this solution, concentration of copper
