| Abstract: |
| With indium-tin alloy scrap reduced from waste ITO target as raw material, mixed indium chloride and zinc chloride salt as electrolyte, indium with purity of 4N5 was prepared after twice electrolysis by molten salt electrolysis. In comparison with the conventional aqueous electrolysis, the productivity of the process under study is improved at least twice with no waste water outlet. |
