Abstract

The electrolytic cell features a top inserted graphite anode and a cathode, Mg-Pb alloy, placed at the bottom of the cell to reduce recombination of magnesium and chlorine in the inter-electrode region. The process involved the electrolysis Of M902 to form an Mg-Pb alloy that is heavier than the electrolyte and a subsequent refining of the alloy to obtain electrolytic grade magnesium. To achieve metallic magnesium production rate with the present cell, that is comparable with the conventional methods, higher current densities have to be used with the present system. The effects of current density on the cell performance have been determined in the present study.
