  "textContent": "Provided is a treatment method whereby it becomes possible to recovery copper, nickel and cobalt, which are valuable metals, contained in a lithium ion battery waste and to separate copper, nickel and cobalt from one another effectively. A method for treating a lithium ion battery waste according to the present invention includes: an alloy production step S1 of introducing the lithium ion battery waste into a furnace and then melting the lithium ion battery waste by heating, thereby producing an alloy containing copper, nickel and cobalt; and an electrolytic purification step S2 of subjecting the alloy to such an electrolytic treatment that the alloy is charged as an anode into a sulfuric acid solution and then electricity is conducted between the anode and a cathode to electrodeposit copper contained in the alloy onto the cathode, thereby separating nickel and cobalt from each other.",
