ABSTRACT:
An electrolytic process is provided for extracting magnesium metal from magnesium-containing aluminum alloys, in which magnesium oxide which is inherently and undesirably formed during electrolytic demagging of an aluminum alloy is destroyed in situ, and a regenerating process is performed within the same electrolytic demagging cell. The magnesium oxide is reacted with a rare earth chloride within the electrolyte to form magnesium chloride and rare earth oxychloride, which are then electrochemically decomposed to form rare earth chloride and molten magnesium which can be recovered from the demagging cell. Intermittent regeneration of the electrolyte substantially re-establishes the original electrolyte formulation. Thereafter, the demagging cell again reverts to the demagging process by which the aluminum alloy is electrolytically demagged to form molten magnesium metal.
