为了更好地于湿法炼锌过程中回收镓、锗，研究采用一种新型镓、锗萃取剂G3815，实现分步萃取分离酸性水溶液锗和镓。研究表明，通过水相酸度调节，镓、锗的萃取率可分别达到92%和98%，使镓、锗浸出-萃取实现闭路循环，省去了碱中和工序，降低了碱耗、酸耗，减少了废水排放。

In order to recover Ga and Ge from zinc hydrometallurgy,a new extractant G3815 has been developed in this paper. The Ga and Ge can be separated and enriched from acidic aqueous solution respectively. The results show that the extraction rate of Ga and Ge can reach 92% and 98% respectively by controlling aqueous phase acidity. The closed circulation of Ga and Ge leaching-extraction has been realized. The alkali consumption, acid consumption and wastewater discharge also can be decreased through the process in this paper.
