| Abstract: | The bench-scale experiment was conducted for enrichment and recovery of germanium in hot acid leaching and zinc-smelting with iron vitriol method. The flowsheet is smoothly during 10 periods of cyclic test. The loss of Ge in halotrichite residue was less than 5.0%, precipitating iron by using ferric potassium alum instead of common Na or ammonium alum. Ge and Ag were all enriched in the high acid leaching residue, and their grades are 0.0325% and 0.162%, respectively. |
