摘要: Provided is a method for efficiently recovering metals from lithium ion battery waste while reducing the use of sodium hydroxide as a pH adjuster.
A method for recovering metals from lithium ion battery waste includes wet processing of leaching metals containing lithium from lithium ion battery waste with an acid, and extracting the metals from the metal-containing solution in which the metals are dissolved, in which the lithium extracted in the wet processing is used as a pH adjuster used in the wet processing.-

摘要: Provided is a method for obtaining a solution having a high concentration of nickel and/or cobalt from an alloy that contains copper as well as nickel and/or cobalt, in a waste lithium-ion battery or the like. A method for treating an alloy according to the present invention comprises: a leaching step S1 for subjecting an alloy that contains copper as well as nickel and/or cobalt to a leaching treatment by using an acid solution in the presence of a sulfiding agent to obtain a leachate and a leaching residue; and a reduction step S2 for adding a reducing agent to a part of the obtained leachate and performing a reduction treatment to obtain a post-reduction solution and a reduction residue, wherein in the leaching step S1, the leachate that has not been provided in the reduction treatment in the reduction step S2, is repeatedly used as part or all of the acid solution added in the leaching treatment.
