新型镓锗萃取剂G315的应用研究

Study on application of a new extractant G315 for gallium and germanium

我国湿法炼锌过程中的镓锗一直无法得到有效地综合回收.采用新型镓锗萃取剂G315,从炼锌系统含镓、锗的溶液中萃取分离镓锗,研究表明,镓、锗的萃取率可分别达到95%和98%.解决了目前镓锗萃取剂如YW100消耗量大及对锌系统影响大等问题.

<Abstrcat> The Ga and Ge can not been comprehensively recovered from zinc hydrometallurgy. A new extractant G315 has been developed in BGRIMM (Beijing General Research Institute of Mining and Metallurgy) and solvent extraction experiments were conducted from solution containing Ga and Ge in zinc metallurgy. The results show that the extraction rate of Ga and Ge can reach 95% and 98% respectively. The new extractant solves the problems such as high YW100 consumption and great effect on zinc metallurgy.
