Title:
METHOD FOR TREATING LITHIUM ION BATTERY WASTE
Document Type and Number:
WIPO Patent Application WO/2019/102764
Kind Code:
A1
Abstract:
Provided is a method whereby it becomes possible to treat a lithium ion battery waste more efficiently and stably while reducing the loss in the collection of a valuable metal, e.g., nickel and copper, in the collection of the valuable metal from the lithium ion battery waste utilizing a treatment in a copper smelting process. 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.
