Pidgeon Process an overview ScienceDirect Topics

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 Production by the Pidgeon Process Involving

20 years the Pidgeon process achieved a strong revival, particularly in China as the major producer of Mg, reaching 72.5% of the world primary production of this metal, which in 2006 amounted to 726 000 tons.4 The advantages of this silicothermic process are, besides the plentiful occurrence of

New process for safer and continuous magnesium production

Currently, 85% of Mg comes from China. The Western Magnesium process begins with mined dolomite (calcium-magnesium carbonate), which is crushed and calcined (thermal decomposition) to make MgO. The MgO is combined with ferrosilicon, a reductant that is also used in the Pidgeon process, and a catalyst, and formed into briquettes.

magnesium processing Techniques & Methods Britannica

Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one-third less. With a density of only 1.738 grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal close-packed (hcp) crystalline structure, so that, like most metals of this structure, it lacks ductility when worked at lower temperatures.
