摘要
对锗的氯化蒸馏残液中的有价金属回收工艺进行了研究,结果表明,经两次萃取分离和多次反萃取分离后,原料中的铟、锡等达到综合回收,所得铟的纯度达98%.
In the process of the chlorination distillation of the Ge,the valuable metal was immersed.Because of quality of this solution is the system of high HCl.it is a difficult problem to recycle the all valable metal in this system.The study uses extraction to recycle the all valable metals.The re-cycling efficiency is high,the seperation is thoroughgoingand the benefit is remarkable.
