用Ｋｅｌｅｘ１００从高碱度铝酸钠溶液中萃取回收镓，反萃获得的含镓液经适当处理后电解得纯度为９９．９９％金属镓。萃取体系引入加速剂后可以加快萃取速率。
Using Kelex100 to extract and recover gallium from the high basicity sodium aluminate solution, the gallium-containing solution obtained after stripping is properly treated and electrolyzed to obtain a purity of 99.99% of metal gallium. Extraction system to accelerate the extraction rate can be accelerated.
