공급원료로 산화 마그네슘 및/또는 부분적으로 탈수된 염화마그네슘을 이용하여 전해 마그네슘의 전해 생성물을 제조하는 방법이 개시된다. 염화마그네슘, 염화칼륨 및 임의의 염화나트륨을 함유하는 전해액을 이용함으로써 마그네슘을 생성한다. 상기 마그네슘은 MgCl-KCl 전해액 하부의 용융된 마그네슘 합금으로 흡수된다. 양극 전해조를 사용하여 실시하는 경우, 순수한 마그네슘은 제2의 용융된 염 전해액을 통하여 마그네슘 합금으로 부터 마그네슘이 수집되는 제2 전해액의 상부 전극으로 이동하게 된다. A process is disclosed for the electrolytic production of magnesium utilizing magnesium oxide and/or partially dehydrated magnesium chloride as a feedstock. An electrolyte containing magnesium chloride, potassium chloride and optionally sodium chloride is employed so that magnesium is produced. The magnesium is absorbed into a molten magnesium alloy cathode layer underlying the MgCl2-KCl electrolyte. In a bipolar embodiment, pure magnesium is electrolytically transported from the magnesium alloy through a second molten salt electrolyte to an overlying electrode where the magnesium collects as a pool on the second electrolyte.
