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 23.10% and 22.1%, respectively after electrogenera- tive leaching for about 10 h under the present conditions.展开更多
