Dolomite

Calcined Dolomite is most commonly utilized for manufacturing refractory bricks required for lining of furnaces and boilers. It has been produced by calcining dolomite at extremely higher temperatures. This powder finds application in steel & iron, sugar, paper, aluminum, paint formulating, leather & textile, and chemical industries. Calcined Dolomite is a type of anhydrous carbonate mineral having calcium magnesium carbonate. It is also used for gasification of biomass for tar destruction at higher temperatures. This mineral has specific gravity range of 2.84-2.86 and is poorly soluble in dilute HCl. It also acts as a catalyst and base material for various industries.

Dolomite Lumps are widely utilized as ornamental stones, a source of magnesium oxide, and as concrete aggregate. They appear white to grey in color with hardness of 3.5 to 4 on Mohs scale. These lumps are crushed in desired grain size and used a base material during road construction, railroad ballast, and rip-rap. They also find application in chemical industry for acid neutralization purpose. Dolomite Lumps are widely utilized as a source of magnesium for live stock, fluxing agent in metal processing, and in manufacturing of glass, brick, and ceramics.

Dolomite Powder is a double carbonate of magnesium & calcium having white colored appearance. It is widely utilized as a chief refractory material for furnace linings and in manufacturing of refractory bricks as well. In blast furnaces, it is used as a fluxing agent. By reacting calcined dolomite with sea water, magnesite can be produced. It has very high melting temperature of about 900 degrees Celsius. When used in furnaces or ladle, this compound can withstand temperature as high as 1700 degrees Celsius. Dolomite Powder is generally applied as outer lining in refractories for having low thermal conductivity.

Dolomite Sand is most commonly used as packing sand below concrete & paving, trenches filling purpose, and as a compacted sub base. It contains good amounts of calcium & magnesium and can also be used for agricultural purposes. This sand can also be utilized for smelting iron and steel. High quantity use of this dolomite is in production of float glasses. In aquariums, Dolomite Sand helps in buffer changes for pH of water. It also serves as catalyst for tar destruction in biomass gasification at extremely high temperature. This sand can easily be dissolved in slightly acidic water.
