ABSTRACT:
Production of pure metals through electro-winning and electro-deposition is accomplished by electrolytic deposition of metal over a reusable stainless-steel plate (cathode). Metal is deposited on both faces of the cathode, as well as on its edges, creating problems when removing the deposited metal. Breaking the deposited edges to remove the metal deposited on both faces produces irregular edges, folding and damages to the surface of the cathode, requiring re-processing, increasing costs of the deposited metal, as well as repairs or replacement of the cathodes. This invention includes a structure made of insulating material to which are fixed electrically energizable cathode guidance profiles with a cross-section similar to an omega and which house the edges of the cathodes, holding them in position during the process.
