ABSTRACT:
A process is disclosed for the electrolytic production of magnesium utilizing magnesium oxide and/or partially dehydrated magnesium chloride as a feedstock. An electrolyte containing magnesium chloride, potassium chloride and optionally sodium chloride is employed so that magnesium is produced. The magnesium is absorbed into a molten magnesium alloy cathode layer underlying the MgCl.sub.2 -KCl electrolyte. In a bipolar embodiment, pure magnesium is electrolytically transported from the magnesium alloy through a second molten salt electrolyte to an overlying electrode where the magnesium collects as a pool on the second electrolyte.
