A New Application For Flotation Of Oxidized Copper Ore

2013-12-24  In this study, the flotation of oxidized copper ore obtained from Ergani CopperMining Company in Turkey was performed. This ore contains 2.03% copper, 0.15%cobalt and 3.73% sulfur. An effective processing method has not been found to recovercopper and cobalt from this ore, which has been stockpiled for 40-45 years in the idledplant. It was established that recovery of copper and cobalt from this ore withhydrometallurgical treatment is not economical, so using flotation to increase theconcentration of copper and cobalt was chosen. When flotation of the oxidized copperore was performed under standard operating conditions in the plant, good results werenot obtained. Because of this, the flotation of samples obtained from sulfurized mediumcontaining 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 mediumwere concentrated. In this solution, concentration of copper and cobalt
