ABSTRACT:
Magnesium is produced by decomposition of magnesium chloride contained in an electrolyte. The magnesium chloride containing electrolyte is provided in a refractory lined electrolytic cell having an anode and a cathode wherein magnesium is produced at the cathode and chlorine at the anode, the magnesium accumulating in a layer on the surface of the electrolyte. A shroud having a skirt portion therein formed from a nitride-based refractory projects into the electrolyte such that chlorine produced at the anode is removed from the cell without contacting the molten magnesium layer, the shroud being resistant to attack by molten magnesium, electrolyte and gases emanating therefrom.
