Flotation Oxidised Copper Ore - arbeidsprobleem.nl
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining 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 recover copper and cobalt from this ore, which has been stockpiled for 40-45 years in the idled plant.
A New Application For Flotation Of Oxidized Copper Ore
It was established that recovery of copper and cobalt from this ore with hydrometallurgical treatment is not economical, so using flotation to increase the concentration of copper and cobalt was chosen. 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 ...
