Embodiment Construction
[0020] A method for electrolytic nickel deposition of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] Such as figure 1 , figure 2 As shown, the purpose of the present invention is to provide a Ni9996 electrolytic nickel production method, the anolyte generated in the electrolytic process is diffused and dialysis to make the pH reach 2.5-3.5, and enter the electrolytic cell as the electrolytic catholyte to produce high-quality electrolytic deposition. nickel. The cathode of the electrowinning cell is not covered with a diaphragm bag, and the anode is a titanium-based iridium-coated anode. After diffusion dialysis, the anolyte recovers a sulfuric acid concentration of 16-28g / L and returns to the front-end leaching process for batching. After industrial application, the chemical quality and physical appearance quality of electrodeposited nickel are improved, the process is optimized, and the production an...
