Pharmacology
Magnesium is an alkaline earth metal, Magnesium is important for many biochemical functions and reactions, for bone and muscle function, protein and fatty acid formation, activation of B vitamins, blood clotting, insulin secretion, and ATP formation. More than 300 enzymes require magnesium for catalytic action. The adult daily requirement is about 300 mg/day. Magnesium is found in many green plants, vegetables, and seeds, chlorophyll is a magnesium-centered porphyrin compound. Magnesium salts are used for magnesium deficiency supplementation. (NCI04)
How it is made
Electrolysis of magnesium chloride obtained from sea water, lake, or well brines (primary), thermal reduction of ores (primarily dolomite) with ferrosilicon (primary), recovery from old & new magnesium & aluminum based scrap (secondary)
Commercial production by electrolytic reduction of magnesium chloride or thermal reduction of magnesium oxide. First obtained in metallic form by Davy in 1808 by electrolyte reduction of magnesium oxide with mercury cathode. Prepn: Deville et al. in Gmelin's, Magnesium (8th ed.) 27A, 121 (1937).
Extracted from well brines & sea water, which is filtered & treated with slaked lime, precipitating the metal as magnesium hydroxide. (This)...converted to the chloride by...hydrochloric acid & the metal is extracted by electrolysis.
