| Abstract: |
| Tellurium-bearing lixivium of copper anode slime by oxidation leaching with sulfuric acid was used as raw materials to prepare tellurium powder with grade of 99.75% by processes of copper removal by electrolysis, tellurium reduction precipitation with sulfur dioxide, selenium removal by sodium sulfite, and copper and arsenic removal by washing with hydrochloric acid. |
