Most magnesium comes from seawater which is composed of 0.13 percent of the element in the form of magnesium chloride. It can also be found in natural minerals such as dolomite and magnesite in the form of magnesium oxide.Magnesium can be produced through several different methods such as the electrolytic method, the thermal-reduction method or the most commonly used Pidgeon method.n this process, magnesium is collected from a condenser on the outside of a furnace. High priority magnesium can be attained from the condenser since vapor pressure of impurities that may be in the magnesium are low under the conditions of the tank. The largest producers of magnesium are China, Russia and Canada.

Magnesium is too reactive to occur in nature as an element, but its compounds are common. At 2.5%, magnesium is the eighth most abundant element in the earth's crust. It is the third most abundant element in sea water which averages about 0.13% magnesium by weight.agnesite (MgCO 3) is an ore for magnesium production and the source of a range of industrial minerals. When pure, magnesite contains 47.8% magnesium oxide and 52.2% carbon dioxide.

Today, magnesium can be extracted from the minerals dolomite (CaCO 3 ·MgCO 3) and carnallite (KCl·MgCl 2 ·6H 2 O), but is most often obtained from seawater. Every cubic kilometer of seawater contains about 1.3 billion kilograms of magnesium (12 billion pounds per cubic mile).lthough it is the eighth most abundant element in the universe and the seventh most abundant element in the earth's crust, magnesium is never found free in nature.

Magnesium and other magnesium compounds are also produced from seawater, well and lake brines and bitterns.&nbsp Magnesium compounds, primarily magnesium oxide, are used mainly as refractory material in furnace linings for producing iron and steel, nonferrous metals, glass, and cement.inks. Subscribe. Magnesium (Mg) is the eighth most abundant element and constitutes about 2% of the Earth's crust, and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance.

This is a toxic compound, and it is also very flammable in air. Solubility of magnesium and magnesium compounds. Magnesium is mainly present as Mg 2+ (aq) in watery solutions, but also as MgOH + (aq) and Mg(OH) 2 (aq). In seawater it can also be found as MgSO 4.Water solubility of magnesium hydroxide is 12 mg/L.Other magnesium compounds are clearly more water soluble, for example magnesium carbonate (600 mg/L).his is a toxic compound, and it is also very flammable in air.

Natural Occurrence. Magnesium is the eighth most abundant element in the earth's crust but does not occur uncombined in nature. It is found in abundance in the minerals brucite, magnesite, dolomite, and carnalite. It is also found (as the silicate) in asbestos, meerschaum, serpentine, and talc.agnesium chloride is found in seawater, brines, and salt wells. Mineral waters often contain salts of magnesium; the magnesium ion imparts a bitter flavor. Magnesium is a constituent of the chlorophyll in green plants and is necessary in the diet of animals and humans.

Magnesium is the eighth-most-abundant element in the Earth's crust by mass and tied in seventh place with iron in terms of molarity. It is found in large deposits of magnesite, dolomite, and other minerals, and in mineral waters, where magnesium ion is soluble.agnesium is the eighth-most-abundant element in the Earth's crust by mass and tied in seventh place with iron in terms of molarity.

The Pidgeon process is most commonly used for production of magnesium due to the fact that its operation is relatively easy, versatile and has low capital cost. This process is also high in energy consumption and has low productivity.In this process, magnesium is collected from a condenser on the outside of a furnace.High priority magnesium can be attained from the condenser since vapor pressure of impurities that may be in the magnesium are low under the conditions of the tank.
