Abstract

1412848 Electrolytically producing metal in a molten halide electrolyte CONZINC RIOTINTO OF AUSTRALIA Ltd 11 April 1973 [17 April 1972] 17424/73 Heading C7B In electrolytically producing a metal (such as Mg, Al, Pb, Bi, Zn, Ce or Ga) as a liquid phase in a molten halide electrolyte, the electrolysis is effected with at least one pair of spaced, substantially parallel electrodes, the opposed surfaces of which are inclined at an angle of from 5 to 30 degrees to the vertical, and gas formed at the inter-electrode space is discharged upwardly into a gas separation chamber disposed above the inter-electrode space, the dimensions of the chamber being such as to provide sufficient surface area and depth of liquid electrolyte therein above the cathode to permit separation of gas from the electrolyte in the chamber at substantially the same rate as the gas is produced in the inter-electrode space. By the process, back-reaction between the gas and electrolytically produced metal is substantially prevented and current efficiency is increased. The interelectrode spacing may be less than 2 inches. Fig.3 shows a cell comprising an anode 1 and cathodes 2. Fig.5 shows a cell comprising an anode 1, cathodes 3, bipolar electrodes 2 with insulating supports 6 and a refractory lined steel shell 4. The examples are of producing Mg from MgCl 2 - KCl-LiCl melts and Al from an AlCl 3 -NaCl-KCl melt.
