The present invention relates to a contact bar assembly for use in a multi-cell electrolytic system for recovery of metal, to a system including the contact bar assembly, and to a method of using the assembly and system. The contact bar assembly includes a base cap board, a primary bar having a plurality of primary bar structures formed thereon, an auxiliary bar having a plurality of auxiliary bar structures formed thereon, and a top cap board, wherein the base cap board includes slots to receive the primary bar and the auxiliary bar, and wherein the top cap board includes a plurality of openings to receive the plurality of primary bar structures and the plurality of auxiliary bar structures. A system includes the contact bar assembly, an anode assembly, a cathode assembly, and a tank.

Contact bar assembly, system including the contact bar assembly, and method of using same

An electrode for use in producing copper in either a conventional electrowinning cell or the direct electrowinning cell is provided. The electrode includes a hanger bar and an electrode body coupled with the hanger bar. The electrode body includes at least one conductor rod having a core and an outer layer surrounding the core and a substrate coupled with the conductor rod.

Anode structure for copper electrowinning

Accordingly, in various embodiments, the present invention provides methods for making electrochemically active materials. Methods include making an electrochemically active material by reacting a platinum group metal salt in a organic solvent to yield a mixture, then heating the mixture to create a metal-organic solvent complex and an acid, followed by removing at least a portion of the acid, and yielding an electrochemically active material comprising the metal-organic solvent complex. In an exemplary embodiment, the resulting electrochemically active material may be used for coating an electrode.

Electrochemically active composition, methods of making, and uses thereof

Various embodiments provide an electrode comprising a conductive substrate, a first layer of a mixture comprising iridium oxide in a crystalline phase and tantalum oxide in an amorphous phase on a portion of an outer surface of the conductive substrate, and a second layer of the mixture comprising iridium oxide in an amorphous phase and tantalum oxide in an amorphous phase on an outer surface of the first layer.
