Abstract:
The present invention provides a method for removing copper from lithium ion battery scrap containing copper, comprising a leaching step of adding the lithium ion battery scrap to an acidic solution and leaching the lithium ion battery scrap under a condition that an aluminum solid is present in the acidic solution; and a copper separating step of separating copper contained in the acidic solution as a solid from the acidic solution, after the leaching step.
