| Abstract: | Used waste hydrochloric acid as raw materials, which producted by chlorination and distillation of germanium mist and dust. Took the scrap iron as the reductant. Recovered valuable metal from the waste acid. Strengthed oxidation chlorination and distillation for recovery of germanium tetrachloride. The comprehensive recovery rate of germanium was 94.10%. Meanwhile, produced the liquid ferric chloride used as purifying agent. |
