accounted for 30% of primary magnesium metal consumption. Structural uses of magnesium (castings and wrought. products) accounted for 18% of primary metal consumption, desulfurization of iron and steel, 12%, and other uses, 6%. Secondary production accounted for .
It is found in large deposits in minerals such as magnesite and dolomite. The sea contains trillions of tonnes of magnesium, and this is the source of much of the 850,000 tonnes now produced each year. It is prepared by reducing magnesium oxide with silicon, or by the electrolysis of molten magnesium .
Magnesium Oxide from Dolomite Production . Magnesium oxide, or magnesia, is a white solid mineral that occurs naturally as periclase and is a source of magnesium. It has an empirical formula of MgO. It is formed by an ionic bond between one magnesium and one oxygen atom.
