Inventor: YOKOTA TAKUYA
IPC: C22B3/00
Filed: 2015-09-29
Abstract: An object of the present invention is to provide a method for leaching lithium ion battery scrap and a method for recovering metals from the lithium ion battery scrap, which can effectively reduce treatment costs. The method for leaching the lithium ion battery scrap according to the present invention comprises leaching the scrap of the lithium ion battery containing nickel and/or cobalt and manganese and/or iron in an acidic solution, the method comprising a metal leaching step of leaching nickel and/or cobalt by adding the scrap to the acidic solution, so that manganese and/or iron is first leached to allow metal ions of manganese and/or iron to be present in the acidic solution, and then contacting nickel and/or cobalt with the metal ions of manganese and/or iron in the acidic solution containing the metal ions of manganese and/or iron, wherein in the metal leaching step, nickel and/or cobalt is leached based on an oxidation-reduction reaction of nickel and/or cobalt with the metal ions of manganese and/or iron, and wherein, in the metal leaching step, after manganese and/or iron are leached, the metal ions of manganese and/or iron are precipitated as oxides by oxidation.
