  • Magnesium refining process
    Patent number: 4695320
    Abstract: Disclosed is a process for refining magnesium crude containing between about 0.7 and 1.5 wt. % calcium. The process includes mixing a flux containing from about 55 to 85 wt. % magnesium chloride and 45 to 15 wt. % alkali chlorides into a molten body of the crude. Refined magnesium is thereby produced, as well as a sludge containing calcium chloride which never has a liquidus exceeding the temperature of the molten body.
