ABSTRACT:
An electrolytic cell is provided for the electrochemical separation of selected metals from electrodissociatable compounds thereof in the molten state utilizing as electrode separator a plurality of solid electrolyte tubes which, under the influence of an electrical potential, are permeable to the flow of selected cations, but impermeable to fluids and the flow of anions and other cations. Electrical switching means are provided with each tube for starting and stopping production of molten metal therein, and for providing a removable electrical path between a cathodic element of the cell and the molten metal in each tube.
