Abstract
A method is disclosed for the production of magnesium in which a magnesium chloride (which may be partially dehydrated) and/or magnesium oxide-containing feedstock is reacted with an electrolyte consisting essentially of magnesium cations, lithium and/or calcium cations, and fluoride and chloride anions, whereby the magnesium chloride and/or magnesium oxide react with and dissolve in the electrolyte, and lithium or calcium initially is produced electrochemically and transiently at the cathode and reacts chemically with magnesium cations in the electrolyte to produce magnesium metal. Thus, the method essentially involves a first electrochemical step to produce lithium or calcium metal and a subsequent second chemical step in which lithium or calcium reacts with magnesium fluoride in the electrolyte to produce magnesium metal.
