| Abstract: |
| An effective method of separation indium and arsenic,antimony,tin from the secondary zinc oxide slag acid lixivium has been achieved by sulphuration process.The effects of initial acidity,the sort and quantity of sulfide,the time of reaction are tentatively investigated.The results show that the removal rate of antimony,arsenic and tin is 100%,98% and 93%,respectively,the lost rate of indium is less than 2% under the following conditions: room temperature,initial acidity is 2.0 mol/L,ZnS is 1.3 times mole ratio than the theoretical,mixing time is 10 min. |
