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.

Abstract: An apparatus for recovering a metal, which comprises a metal-recovering board (2) having an electrodeposition surface (2a, 2t) for the attachment of a metal component (R) precipitated from a solution and an insulating material (2b) formed around a pattern of the electrodeposition surface (2a, 2t). The metal-recovering board (2) is immersed in a metal-containing solution in an electrolytic treatment vessel (1), and thereby the metal in the solution is selectively precipitated on the electrodeposition surface (2a, 2t) and is converted to a bulk. The resultant metal bulk is scraped together for recovery with a blade (6) in a form as it is. The above apparatus for recovering a metal can be suitably used for recovering a metal in a solution in a state allowing easy reuse with good efficiency.

Abstract: A three-dimensional electrode with higher strength and higher toughness is provided. The three-dimensional electrode is fabricated by bending a plurality of snicks which are formed in a plate-like electrode substrate toward the same direction. The stabilization of the positional relation among the elements generated by the three-dimensional electrode neither mechanically damages the membrane nor causes the insufficient current supply. The three-dimensional electrode is preferably used for brine electrolysis and white liquor electrolysis.

Abstract: This disclosure provides a joining area and method between copper and stainless steel or titanium, as well as the permanent cathode obtained, where said joining area is made of a first zone of a copper-nickel (Cu—Ni) alloy, an intermediate zone with a mostly nickel alloy or pure nickel and a second zone made of a stainless steel-nickel alloy, which is the result of the participating materials being cast in an arc welding process, for example TIG, MIG or manual arc using electrodes of nickel as welding contributor between said materials and their space arrangement, that is to say, leaving a separation between the materials when performing the welding process, thus ensuring as follows: a) greater tensile strength, b) a substantial improvement of corrosion resistance of the joint welding, and c) improvement of conductibility, which can be improved still further by modifying the straight design of the conducting bar by providing it with the “horn”-type shape.

Abstract: The method relates to the obtaining of a good current contact on the support bar of a cathode used in electrolysis. In this method a highly electroconductive layer is formed on the contact piece on the end of the support bar of the cathode, especially at the point that comes into contact with the electrolysis cell busbar. The electroconductive layer forms a metallic bond with the contact piece of the support bar. The invention also relates to the cathode support bar, wherein a highly electroconductive layer is formed to the contact piece on the end of said bar, in particular the area that touches the electrolysis cell busbar.

Abstract: A cathode for use in the refining or winning of metals, typically used in the electro-refining or winning of copper, comprising a substantially flat deposition plate fixedly attached along an upper edge thereof to an elongate hanger bar thereby defining a connection. A protective cladding is attached to the deposition plate and at least partially surrounding the hanger bar such that a cavity is defined in the region of the connection. A corrosion resistant material fills the cavity. In this manner the corrosion resistant material prevents corrosive substances from penetrating the connection. The corrosion resistant material prevents corrosive electrolytic solution and other liquids from corroding the conductive connection between the deposition plate and the hanger bar which would otherwise reduce efficiency of the cathode.
