| Abstract: | Ca, Mg can be removed by chemical precipitation in the production of nickel sulfate, but F- can be brought into nickel sulfate. The method for removal of Ca, Mg by silicic acid congealed gel was reported in this paper, the content of Ca, Mg, F- can reach the requirement of battery material. The orthogonal experiments were carried out. The optimal conditions： Ph=l, and reaction time is 1.5 hours, and reaction temperature is 90-95 22. |
