ABSTRACT:
A method for the electrolytic production of metal, including electrolyzing, between anodic and cathodic surface areas, a compound of the metal dissolved in a molten solvent, the electrolyzing being performed at a temperature such that the metal is formed in the molten state, the metal collecting in a molten metal pad, wherein the improvement includes the provision of cathodic surface area in the form of an array of elements protruding out of the pad into the solvent toward the anodic surface area for establishing a series of locations at which the anode-cathode distance is up to 11/4 inches.
