本工艺是研究在 H_2SO_4介质中用全萃法萃取锗和镓,萃取剂为 P204,协萃剂是 YW100,反萃剂分别为氨水和 H_2SO_4,原料液为株洲冶炼厂萃铜余液,其锗、镓含量为:Ge0.095～0.12g/L、Ga0.13～0.16g/L。锗和镓的日处理量分别为2.9和2.54m~3,锗连续运转60天,镓连续运转30天,锗和镓的平均萃取率分别为97.5和95%,反萃率分别为56和～100%,为试生产提供了可靠的依据。
The process is to study the extraction of germanium and gallium by full-extraction method in H 2 SO 4 medium, the extraction agent is P204, the co-solvent is YW100, the stripping agent are ammonia and H_2SO_4 respectively, the raw material liquid is Cu-leaching liquid of Zhuzhou smelter, the germanium , Gallium content: Ge0.095 ~ 0.12g / L, Ga0.13 ~ 0.16g / L. Germanium and gallium daily processing capacity of 2.9 and 2.54m ~ 3, germanium continuous operation for 60 days, gallium continuous operation for 30 days, germanium and gallium average extraction rates were 97.5 and 95%, stripping rates were 56 and ~ 100%, to provide a reliable basis for pilot production.
