Extraction of Magnesium-

The extraction of magnesium mainly falls into two groups, i.e. electro-refining (for magnesite) and thermal reduction process (for dolomite). Brief introduction will be given in the following passage. Thermal reduction process is represented by Pidgeon process, named after its inventor Dr. Lloyd Montgomery Pidgeon.

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.
