Abstract
Provided is a method of recovering valuable metals from IZO scrap in which valuable metals are recovered as indium and zinc metals or suboxides by performing electrolysis using an insoluble electrode as an anode and an IZO scrap as a cathode. Specifically, this method enables the efficient recovery of indium and zinc from IZO scrap such as an indium-zinc oxide (IZO) sputtering target or IZO mill ends that arise during the manufacture of such a sputtering target.
