METHOD FOR COLLECTION OF VALUABLE METAL FROM ITO SCRAP |
摘要 |
<p>Disclosed is a method for collecting a valuable metal from an indium-tin oxide (ITO) scrap, characterized by conducting the electrolysis of the ITO scrap in an pH-adjusted electrolyte solution to collect a mixture of indium hydroxide and tin hydroxide or metastannic acid and, if required, roasting the mixture to collect a mixture of indium oxide and tin oxide. It becomes possible to provide a method for collecting indium hydroxide and tin hydroxide or metastannic acid or indium oxide and tin oxide 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.</p> |
