Magnesium is electrolytically produced from a salt melt comprising magnesium chloride by the use of an electrolyzer having at least one electrolysis compartment and at least one metal separating compartment separated from the electrolysis compartment by a partition wall. Magnesium chloride is fed in solid form in a direction counter current to the flow of chlorine gas liberated during electrolysis to a melting room or chamber in the electrolysis compartment arranged such that contact between the magnesium chloride and the anodes of the electrolyzer is avoided. Flow patterns are produced in the melt to ensure that sludge forming impurities in the fed magnesium chloride are continuously removed from the electrolysis compartment to the metal separating compartment.
A method for the electrolytic production of magnesium from a salt melt comprising magnesium chloride by the use of an electrolyzer having at least one electrolysis compartment and at least one metal separating compartment separated from said electrolysis compartment by a partition wall, said method comprising:
An electrolyzer for the electrolytic production of magnesium from a salt melt, said electrolyzer comprising:
