A method for electrolytically obtaining magnesium metal from an electrolytic bath comprising MgCl2, said method comprising: preparing an electrolytic bath composed of MgCl2 and additional ingredients, such that the bath as a whole exhibits a density greater by 0.02 to 0.10 g/cm3 than magnesium at circumstantial temperatures employed, and an electrical conductivity of 2.4 OMEGA -1cm-1, holding said bath in an arrangement which comprises two spaces separate but in communication with each other, conducting an electrolysis of said bath so that a magnesium metal is deposited cathodically and a chlorine gas, anodically, in a first space, transferring the magnesium metal to the second space to a substantial part as carried under the surface of bath, while the chlorine gas is left to a substantial part in the first space, allowing the bath to dwell in said second space for a time enough for the magnesium to collect to a major part at the surface, and recovering the magnesium metal from the surface in the second space. |
