Abstract
Provided are a method of recovering valuable metals from IZO scrap, wherein indium and zinc are recovered as hydroxides by using an IZO scrap as both an anode and a cathode, and performing electrolysis while periodically reversing polarity; and a method of recovering valuable metals from IZO scrap, wherein the hydroxides of indium and zinc obtained by the electrolysis are roasted and indium and zinc are recovered as oxides. Specifically, provided is a method which enables the efficient recovery of indium and zinc from IZO scrap such as a spent indium-zinc oxide (IZO) sputtering target and IZO mill ends arising during the manufacture of such a sputtering target.
