    摘要： Provided is a method of recovering valuable metal from oxide system scrap including the steps of performing electrolysis using an insoluble electrode as an anode and an oxide system scrap as a cathode, and recovering the scrap of the cathode as metal or suboxide. Specifically, this method enables the efficient recovery of valuable metal from oxide system scrap of an indium-tin oxide (ITO) sputtering target or oxide system scrap such as mill ends that arise during the production of such a sputtering target.

    摘要： The present invention relates to a method for treating spent tin or tin/lead stripping solution used in the electronic industry, particularly in the manufacture of printed circuit boards or a lead frames. Said method comprises (i) electrolytically reducing copper ions in the solution to copper at a low temperature; (ii) electrolytically oxidizing Sn2null and Pb2null in the solution at a high temperature to form solid tin and lead oxides and hydroxides; (iii) separating solid tin and lead oxides and hydroxides from the solution; (iv) dissolving tin and lead oxides and hydroxides obtained in step (iii) in a strong alkali or acidic solution; and (v) electrolytically reducing the alkali or acidic solution obtained in step (iv) at a high temperature to recover metallic tin and lead. Also, the filtrate obtained in step (iii) above is useful for preparing fresh tin or tin/lead stripping solution.
