Abstract: A system for buffing a cathode including a lifting assembly, a carriage assembly, and a buffing assembly. The lifting assembly is configured to transport the cathode in a substantially vertical direction while the carriage assembly secures the cathode. The buffing assembly is configured to buff the cathode as the cathode is transported in the substantially vertical direction. The buffing system provides for buffing both sides of a cathode simultaneously.

Abstract: An electrochemical cell for producing metal and chlorine from metal ore and a metal chloride includes a cathode, an anode, and a separator. A catholyte includes (i) water, (ii) a metal hydroxide comprising Q, where Q is an alkali metal, an alkaline earth metal, or a combination thereof, and (iii) suspended metal ore particles comprising MxOy where M is a metal and x and y are integers. An anolyte includes (i) water and (ii) a metal chloride comprising Q. An electrowinning process for producing metal and chlorine includes applying a voltage across the electrochemical cell to effect reduction of the MxOy in the cathode compartment to provide the metal M and oxidation of chloride ions in the anode compartment to form Cl2 gas.

Abstract: A method and an apparatus for manufacturing a metallic article involve providing a non-metallic feedstock, for example in the form of an oxide of a desired metal or a mixture of oxides of the components of a desired metal alloy. A manufacturing apparatus has a reduction apparatus for electrochemically reducing the feedstock to a metallic product and a processor for converting the metallic product to a metallic powder. The powder is fed into an additive-manufacturing apparatus for fabricating the metallic article from the metallic powder. At least the reduction apparatus and the processor, and preferably also the additive-manufacturing apparatus, are collocated, or located in the same container, or in the same building, or on the same site.

Abstract: Lead from lead acid battery scrap is recovered in two separate production streams as clean grid lead and as high-purity lead without smelting. In preferred aspects, lead recovery is performed in a continuous process that uses an aqueous electroprocessing solvent and electro-refining, and spent electroprocessing solvent can be recycled to the recovery process.

Abstract: Provided are a metal electrodeposition cathode plate, the non-conductive film of which is not susceptible to failure and which can be used repeatedly, and a production method therefor. This cathode plate comprises a metal plate on which multiple disc-shaped protrusions are disposed, and a non-conductive film formed on the non-protrusion flat areas of the metal plate. The minimum film thickness Y of the non-conductive film at positions between the centers of adjacent protrusions is the same or greater than the height X of the protrusions. It is preferred that the height X of the protrusions is 50 μm to 1000 μm.
