摘要：
Proposed is a method for collecting valuable metal from an ITO scrap including the steps of subjecting the ITO scrap to electrolysis and collecting the result as indium-tin alloy. Additionally provided is a method for collecting valuable metal from an ITO scrap including the steps of providing an ITO electrolytic bath and an indium-tin alloy collecting bath, dissolving the ITO in the electrolytic bath, and thereafter collecting indium-tin alloy in the indium-tin alloy collecting bath. These methods enable the efficient collection of indium-tin alloy from an ITO scrap of an indium-tin oxide (ITO) sputtering target or an ITO scrap such as ITO mill ends arisen during the manufacture of such ITO sputtering target.
