An apparatus for electrolytic production of magnesium metal from its chloride comprises at least one externally unwired electrode 22 which is made of graphite alone or graphite-iron composite located between each anode 16 and cathode 17 with the graphite side towards the cathode. The apparatus having a cooling passage 31 for electrolyte which allows the electrolyte to flow outside an electrolysis chamber 7 containing the electrodes, from a bath surface level 29 to the bottom. The bath electrolyte being cooled a little but not enough to solidify, to show increased density so that it flows back down 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. |
