Process for electrolytic recovery of nickel from solution

摘要

The present invention provides a method for electrolytically recovering or winning pure metallic nickel from nickel sulfate-containing solution using an electrolysis cell having nickel electrodes. The cell has at least one anode space, at least one cathode space and a diaphragm disposed therebetween. Certain of the nickel electrodes are employed alternatively as anode electrodes and as cathode electrodes in the anode and cathode spaces, respectively, while maintaining other electrodes as fixed cathode electrodes in the cathode spaces for electro-winning of nickel. Nickel regenerated using the process of the present invention may be employed as anode material in nickel electroplating processes.
