  • Magnesia or magnesium oxide is an alkaline earth metal oxide.
    Magnesium oxide produced is obtained from the calcinations of naturally occurring minerals, magnesite, MgCO3,
    Other important sources of magnesium oxide are seawater, underground deposits of brine and deep salt beds from which magnesium hydroxide [Mg(OH)2] is processed.
  • Magnesia is used in the steel industry as a refractory brick impregnated with tar, pitch, graphite etc to give optimum properties for corrosion resistance in environments of basic slags, BOF furnaces or slag lines of treatment ladles. Magnesia bricks in combination with spinel or chrome are also used in ferroalloy, non-ferrous, glass and cement industries. Castables and sprayables based on magnesia are used for basic refractory linings for steel transfer applications.
  • A Molten Magnesia is air quenched to provide a very large proportion of solid free flowing spheres of fused magnesia, a large percentage of which are smaller than about 35 Tyler mesh, which may be used directly in electrical resistor units without the necessity of crushing and calcining while the larger sized spheres may be crushed if desired and can be used with the uncrushed spheres without being calcined.
  • Fused magnesia particulates are conventionally produced in an electric arc furnace forming a solid ingot from the molten starting material which is thereafter mechanically crushed and ground by various means to a final desired particle size.
  • Fused Magnesite is  produced by melting caustic magnesia. Fused Magnesite finds application as insulating material in tubular heating, elements in the electrical industry and refractory brick linings in steel furnaces. Fused Magnesite is mainly used as an insulating material in the electrical heating industry. The particulate material is packed into the space between the heating coil and the outer tube in a heating element for air or liquids. Such elements are used in IR heaters, grill elements, tubular hot plates, and tubular heating elements for ovens, storage heaters, radiators, continuous-flow heaters, washing machines, coffee machines, electric irons, and industrial liquid heating equipment.
  • Magnesium is the eighth most abundant element and constitutes about 2 percent of the Earth’s crust. It is the third most plentiful element dissolved in seawater, with a concentration averaging 0.13 percent. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance. Magnesium and magnesium compounds are produced from seawater, well and lake brines and bitterns, as well as from the minerals noted above.
  • Magnesite deposits occur in Spain, Pakistan, and the Sudan. Deposits of less than 1 million metric tons (Mt) were reported in Mexico, Iran, the Philippines, Australia, Egypt, and the Republic of South Africa. Small deposits also have been noted in Cuba, Sweden, Norway, Poland, Scotland, France, Italy, Kenya, and Tanzania. The reported estimate of 65 Mt of magnesite (15 Mt magnesium) reserve is based in the United States
