Abstract
A process for reducing magnesium from its compounds, including oxides, ores, sulphates, and chlorides, comprises mixing the powdered compound and powdered calcium carbide with a viscous carbonaceous binder such as tar or other hydrocarbon product, and heating the mixture in a reducing or inert atmosphere and in the absence of moisture, nitrogen, and oxygen, and in some cases under reduced pressure, to distil off the magnesium. The resulting slag may be removed in dry form, or a liquid slag may be obtained by the addition of fluxes such as magnesium or aluminium fluoride. The magnesium vapours may be condensed to metal, or alloys may be obtained directly by condensing the vapour in contact with other molten metal.
