Abstract
The present invention relates to electrolytic recovery of metal, and in particular methods and apparatus for producing cathode plates suitable for such electrolytic recovery. The invention provides a method of providing an electrically conductive coating on a cathode plate comprising inverting and submerging an upper portion of the cathode plate in an electrolytic bath adjacent at least one anode and applying a current to electroplate the upper portion of the cathode plate wherein each anode includes: i) a first base portion adapted to be positioned adjacent to a hanger bar of said cathode plate; ii) a second extended portion connected to and extending from the base portion and adapted to be positioned adjacent a blade of the cathode plate wherein the profile of each anode is shaped such that in use, a consistent thickness of coating is electroplated over said hanger bar and cathode blade.
