| Abstract: | In the experiments of purifying the solution of chlorine leaching and removing iron from nickel concentrate with N235, the effects of organic phase composition on purifying efficiency have been studied. From the results obtained, the optimal organic phase composition is found to be 25% N235+12%isomerous alcohol+63%sulfonic kerosene (V/V) and the saturated content of cobalt in organic phase is 8 g/L. And then the serial experiment is carried out. The results show that at the given organic phase composition, the purified solution contains ρ(Ni)>200 g/L, ρ(Ni)/ρ(Co)>50*!000 and the contents of Cu, Fe, Mn, Zn meet the technical criterion of 1# nickel electrolyte. The cobalt chloride solution contains ρ(Co)>110g/L,ρ(Co)/ρ(Ni)>5*!000 and the enrichment of cobalt has been achieved. The technical process is simple, stable and reliable. |
