<p>In a method for electrolytically obtaining magnesium metal from an electrolytic bath which comprises MgCl2, comprising: preparing and holding a fused bath in an arrangement which comprises two separate spaces, depositing maqnesium metal cathodically and evolving chlorine gas anodically in the first space, transferring magnesium metal carried by the bath to the second space through a channel means arranged between the spaces, and allowing magnesium metal, for recovery, to collect for the major part at the surface of the bath in the second space. The electrolytic bath consists of MgCl2 and NaCl, as well as at least one salt selected from KCl and LiCl but without CaCl2, so composed as to exhibit an electrical conductivity, at least, of 2.4 .OMEGA.-1cm-1 and a density greater by 0.02 to 0.10 g/cm3 than magnesium at the temperatures employed, so that the magnesium metal in transfer may be held for the major part under the surface until the metal enters the second space and ascends to the surface in time in the space.</p> |
