J.W. Evans, in Encyclopedia of Materials: Science and Technology, 2003 5.2 The Production of Magnesium. Magnesium is produced by one of two routes: non-electrolytic ones (the “ Pidgeon process ” or “Magnetherm process”) and by the electrolysis of magnesium chloride dissolved in a mixture of molten chlorides. Steel cathodes and graphite anodes are used in the latter.

Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.

China is the largest producer of magnesium in the world, and supplies currently 40–50% of the world demand for magnesium. Magnesium production in China is based on a thermal process, known as the Pidgeon process. However, the horizontal Pidgeon reduction process currently deployed in China possesses a characteristic, i.e. inefficiency

The reduction ratio was compared between the Pidgeon process and the aluminothermic reduction process with CA2, CA, C12A7 as the main production in the residue. The results of XRD show that the main phase in the reduction residue is CA2, CA, C12A7 and Ca2SiO4, respectively. Consideration of the efficiency of extracting magnesium, the aluminothermic reduction process which is CA2 as the main ...
