	Magnesite - LoveToKnow 1911
		MAGNESITE, a mineral consisting of magnesium carbonate, MgCO 3, and belonging to the calcite group of rhombohedral carbonates.
		The name magnesite as originally applied by J. Delametherie in 1797 included several minerals containing magnesium, and at the present day it is used by French writers for meerschaum.
		Magnesite is a product of alteration of magnesium silicates, and occurs as veins and patches in serpentine, talc-schist or dolomiterock.

	magnesite - Encyclopedia.com
		Caustic magnesite is not thoroughly calcined, 3% to 4% of carbon dioxide being left; mixed with magnesium chloride it makes oxychloride cement, which is extensively used for floorings and as a stucco.
		Magnesite is also used in the manufacture of Epsom salts, face powder, boiler wrappings, and disinfectants.

	MAGNESITE (Magnesium Carbonate)
		Magnesite does not ordinarily form good crystals, but can make up a substantial portion of some rock types.
		Magnesite has the same crystal structure of calcite, hence its inclusion into the calcite mineral group.
		Many of the properties of magnesite are either identical or similar to those of calcite.

		Pure magnesite is theoretically 47.8% MgO and 52.2% CO It is the source of two-thirds of the 9 Mt of magnesia (MgO) used annually throughout the world; 25% is extracted from sea water, with the balance coming from brines or other mineral sources such as serpentinite or brucite.

		It is for this definition of burned and unburned magnesite brick and shapes excluding carbon impregnated magnesite brick and shapes that the aggregate latent demand estimates are derived.
		Based on the aggregate view of burned and unburned magnesite brick and shapes excluding carbon impregnated magnesite brick and shapes as defined above, data were then collected for as many similar countries as possible for that same definition, at the same level of the value chain.
