ABSTRACT:
An apparatus for electrolysis of MgCl.sub.2, comprising an air-tightly sealed shell of metallic material, said shell exhibiting in horizontal cross section a rounded profile which comprises at four portions a curve selected from a quarter-circular arc and a quarter-elliptical arc, means for forcibly cooling said shell from outside, a wall structure which consists of an insulative refractory of a decreased thickness and which is provided along said shell, an electrolysis chamber defined by said wall structure and a pair of primary partitions extending in parallel with each other across the wall structure, a separation chamber provided in adjacency with the electrolysis chamber for stripping magnesium metal from electrolytic bath, at least one pair of anode and cathode arranged in the electrolysis chamber, at least one bipolar intermediate electrode arranged between the anode and cathode, and a top cover provided air-tightly over the electrolysis chamber and the separation chamber, thus allowing as a whole an electrolytic operation at a substantially regulated bath temperature with an increased number of electrodes.
