The present invention provides an apparatus for electrolytic production of magnesium metal from its chloride, which apparatus essentially comprises at least one externally unwired electrode which is made of graphite alone or graphite-iron composite and is placed between each pair of anode and cathode with the graphite side towards the cathode. The apparatus preferably comprises further a cooling passage for electrolyte bath which allows the electrolyte bath to flow outside an electrolysis chamber where the electrodes are contained, from a bath surface level to the bottom. The bath, while it passes there, is cooled a little, not enough to solidify, to exhibit an increased density so that it flows down back into the electrolysis chamber at the bottom, thus forming a continuous upflow along the electrodes, which facilitates separation of products of magnesium metal and chlorine gas and their recovery. Preferred anode construction is also illustrated.
