Abstract Scope |
Due to the close physical and chemical properties of nickel and cobalt, it is difficult to separate them. At present, the main separation methods include ion exchange method, membrane separation method and solvent extraction method. In this study, the solvent extraction method was used for the experiment, in which the nickel cobalt simulation liquid was prepared according to the material liquid data after removing impurities by P204 in the industry, and then the nickel cobalt separation experiment was carried out using the modified Cyanex272 extraction agent. The experimental results show that the optimal extraction conditions are as follows: comparison is 1:1, initial pH value is 5.5, reaction temperature is 25 °C, reaction time is 10 min. Under these conditions, the extraction rate of single-stage cobalt can reach about 96%, and the three-stage extraction rate of cobalt can reach more than 99% after the extraction equilibrium diagram is drawn by experiments. |
