Simultaneous electrogenerative leaching of chalcopyrite concentrate and MnO₂

Abstract

In order to enhance the electrogenerative leaching rate of chalcopyrite concentrate reasonably, the principle of generative process was applied to simultaneous leaching of chalcopyrite concentrate and MnO₂. The results show that Cu²⁺ and Mn²⁺ in addition to electrical energy could be acquired in the simultaneous electrogenerative leaching process. The leaching cell has the open circuit potential of about 1.0 V and gains quantity of electricity of about 700 C. The optimum leaching rates of Cu²⁺ and Mn²⁺ are 23.1% and 22.1%, respectively after electrogenerative leaching for about 10 h under the present conditions.
