Abstract
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.
