Abstract

Magnesium is produced in a two-stage cyclic process by first reducing a material containing magnesia and lime, e.g. dolomite, with aluminium to form magnesium and calcium aluminate slag, the magnesium being distilled off, and then reducing the aluminate slag with carbon in the presence of an auxiliary metal, such as a bath of molten copper, iron or Cu-Al alloy, to form an alloy of aluminium with the auxiliary metal, and calcium carbide as by-product, the alloy being returned to be used as a reducing agent for producing further quantities of magnesium. The reaction components are preferably finely ground, pelletized or briquetted.
