Simultaneous electrogenerative leaching of chalcopyrite concentrate and MnO_2

摘要

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 Cu 2+ and Mn 2+ 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 Cu 2+and Mn 2+ are 23.1% and 22.1%, respectively after electrogenerative leaching for about 10h under the present conditions.
