Description

technical field

[0001] The invention relates to auxiliary equipment for electrolytic deposition equipment in the technical field of chemical industry, belongs to the technical field of environmental protection, and specifically relates to an environment-friendly electrolytic nickel or electrolytic cobalt continuous and stable production process device and process.

[0002] Background technique

[0003] The relatively advanced nickel production method in China is to produce metal nickel by refining hydrometallurgy process. During the production process, according to the chemical properties of nickel, it is easy to be polluted by other metals with similar potential or higher potential. Diaphragm electrolytic structure is used. The diaphragm bag 3 divides the electrolyte solution into the cathode area 1 and the anode area 2, and supplies the electrolyte solution to the cathode area (in the diaphragm bag) through the catholyte high level tank by self-flowing, ensuring that the ...
