METHOD FOR COLLECTION OF VALUABLE METAL FROM ITO SCRAP

摘要

Disclosed is a method for collecting a valuable metal from an indium-tin oxide (ITO) scrap, characterized by collecting an indium-tin alloy by the el ectrolysis of the ITO scrap. Also disclosed is a method for collecting a val uable metal from an ITO scrap, characterized by providing an ITO-electrolyzi ng bath and an indium-tin alloy-collecting bath, dissolving ITO in the elect rolyzing bath, and collecting the indium-tin alloy in the collecting bath. I t becomes possible to provide a method for collecting an indium-tin alloy at high efficiency from an ITO sputtering target or an ITO scrap (e.g., a ITO waste) produced during the production of the ITO sputtering target.
