| Abstract: | For treating the bio-leachate solution with high concentration of Fe and low concentration of valuable metals,Fe was separated from Ni and Co at low temperature and low pH.N235+TBP and kerosene were selected as extraction agent and diluent respectively.The factors that affect separation of Fe from Ni and Co in extraction solvent system consisting of sulphate were investigated.Based on the experimental results,a three-stage cross-flow extraction was carried out.Meanwhile,the conditional factors of the reextr... |
