摘要：

Nickel sulfide ore always accompanies by a large amount of copper, and copper can be often leached simultaneously into the nickel leaching solution. However, because of their similar chemical properties, it is difficult to separate. Here, anion exchange membrane electrolysis was provided to separate copper from solution by controlling the cell voltage. The effects of polar distance, electrolyte temperature, cell voltage and concentrations of copper and nickel on separation of copper-nickel were studied and the optimal operation conditions were obtained. The results show that, for solution containing 25 g/L Cu2+ and 37.5 g/L Ni2+, the total residual Cu concentration in catholyte is depressed to 0.24 g/L and the ratio of PNi/Cu reaches 155.7 under the optimal conditions of polar distance 4 cm, electrolyte temperature 40℃, cell voltage 0.53 V, electrolysis time 10 h. A satisfied effect of separation of copper from nickel is obtained. © 2017, Science Press. All right reserved.
