Abstract: The extraction of the cations such as Fe2+,Mn2+,Zn2+ and In3+ in the simulated sulfate solution by P204 has been examined from a technology solution-reduction solution with adding manganese,that was obtained by reduction of the high leached solution in the hydrometallurgy of zinc without iron residue.The optimum separation conditions have been determined as:(1) component of the organic phase being 30% kerosene+ 70% sulfidized kerosene,(2) extraction temperature being 20 ℃,(3)progressions being 3,(4) ratio of O/A being 3∶1,and (5) extration time being 5 min.Under the optimum extraction conditions,the extration rate of indium is not less than 99.4%.the saturated capacities of P204 on In3+,Zn2+ and Mn2+ were measured for 54.0 mg·mL-1,22.0 mg·mL-1 and 2.0 mg·mL-1respectively.The direct recovery rate of indium for the whole flow sheet arrived at 77.58% and the total recovery rate reached 95.0%,In comparision with the traditional flow sheet the total recovery rate of indium was higher than 20%.

Key words: indium, etraction, hydrometallurgy of Zinc, without iron residue
