| Abstract: | A series of processes were applied to recover germanium and indium from zinc slag with high lead and silicon contents, including zinc neutral leaching, two-stage oxygen pressure leaching, indium extraction, and germanium recovery by calcium salt distillation. The recovery of germanium and indium is 93.2% and 95.6% respectively. The above processes are characterized as green, safe, efficient and economic. |
