Document Type and Number:
Japanese Patent JP4966460
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for recovering valuable metals from waste batteries containing various kinds of valuable metals such as cobalt by electrolytic technique, especially a method for simply, surely, and inexpensively separating cobalt. SOLUTION: This method electrolytically recovers cobalt from a battery material containing cobalt as an electrode material in such a way that a cobalt- containing electrolyte prepared by dissolving the electrode material is electrolyzed in an acidic state under the presence of dissolved chlorine, and cobalt is deposited on a cathode. By this method, cobalt contained in the electrode material of the waste battery is efficiently recovered as high purity cobalt metal at the minimum electric energy.
