Abstract

Official abstract text for this publication.

A method for treating a lithium ion battery waste according to the present invention is a method for treating a lithium ion battery waste using a converter furnace in a copper smelting process, wherein, prior to a treatment for charging a copper mat produced in a flash smelter in a copper smelting process into a converter furnace and blowing oxygen into the converter furnace to produce crude copper, the lithium ion battery waste is introduced into the converter furnace or a ladle that is used for the charging of the copper mat into the converter furnace and then the lithium ion battery waste is burned with residual heat in the converter furnace or the ladle.

First claim

Opening claim text (preview).

1 . A method for treating a lithium ion battery waste using a converter furnace in a copper smelting process, wherein prior to a treatment for charging a copper matte obtained from a flash smelter in the copper smelting process into a converter furnace and blowing oxygen into the converter furnace to obtain crude copper, a lithium ion battery waste is introduced into the converter furnace or a ladle furnace that is used for charging the copper matte into the converter furnace and then the lithium ion battery waste is burned with residual heat in the converter furnace or the ladle furnace. 2 . The method for treating a lithium ion battery waste according to claim 1 , wherein an amount of the lithium ion battery waste introduced into the converter furnace or the ladle furnace is adjusted such that an amount of material of fluorine contained in the lithium ion battery waste becomes an amount corresponding to 10 ppm or more and less than 35 ppm with respect to an amount of material of copper to be supplied to the converter furnace in the copper smelting process. 3 . The method for treating a lithium ion battery waste according to claim 1 , wherein the lithium ion battery waste is discharged to remove an electrolyte solution contained in the discharged lithium ion battery waste and then the lithium ion battery waste is introduced into the converter furnace or the ladle furnace and is burned. 4 . The method for treating a lithium ion battery waste according to claim 2 , wherein the lithium ion battery waste is discharged to remove an electrolyte solution contained in the discharged lithium ion battery waste and then the lithium ion battery waste is introduced into the converter furnace or the ladle furnace and is burned.
