一、前言近年来,利用溶剂萃取提取有色金属已进入实用阶段,其范围已从铀和铜扩大到钴、镍、镓铟等。铟的制取采用中和法,还存在有作业性质、回收率、杂质等关键问题有待进一步改进。因而以溶剂萃取法为目标进行了基础试验。关于铟的溶剂萃取已有不少报导,但都是用盐酸作反萃取液,用硫酸作反萃液的还未见到这样
I. Introduction In recent years, the use of solvent extraction of non-ferrous metals extraction has entered a practical stage, its scope has expanded from uranium and copper to cobalt, nickel, gallium indium and so on. Preparation of indium using neutralization method, there are still operating properties, recovery, impurities and other key issues to be further improved. Therefore, solvent extraction as the goal of the basic test. There have been many reports on the solvent extraction of indium, but all of them are carried out using hydrochloric acid as the stripping solution and sulfuric acid as the stripping solution has not been seen yet
