Magnesite usually forms during the alteration of magnesium-rich rocks or carbonate rocks by metamorphism or chemical weathering. Magnesite is used to produce Magnesium Oxide (MgO), which serves as a refractory material for the steel industry and as a raw material for the chemical industry.
Magnesium oxide (MgO) is one of the most important products of the refractory industry. It is usually produced by thermal decomposition of magnesite (MgCO3) or by a seawater process from Magnesium Hydroxide (Mg(OH)2).
The type of raw material, the temperature of calcination and the impurities mostly affect the physical properties of MgO.
Caustic calcined MgO is burned at temperatures below 900 °C. It is used in fertilizers, as animal feed and as a raw material for various MgO chemicals for the production of pulp and paper, ceramics and cements.
A characteristic property of this MgO type is its moderate to high chemical reactivity.
Because of this reactivity, it is imperative to search for a dry processing technique for the enrichment of the MgO, lest a transformation to Mg(OH)2 take place which influences the product in an undesirable way.
Use of Caustic Calcined Magnesite
Caustic Calcined Magnesite is mainly used to prevent fire board, feed, fertilizer, manhole cover, insulation board, art fence, magnesium sulfate, door core board, composite insulation board, firecracker solid propellant, chicken house, inorganic glass, magnesite tile, grinding wheel Ideal raw materials for molds, artificial marble, power plant boiler flue gas desulfurization, sewage treatment, ventilation pipes, lightweight partition boards, vegetable scaffolding, building materials, ceramic brick bottom powder, steelmaking slag, paper making, biogas tanks, etc. .
Caustic calcined magnesite can be used to make cementitious materials. For example, building materials containing magnesium cement, heat insulation and sound insulation can also be used as ceramic raw materials. After chemical treatment of light burnt magnesium, various magnesium salts can be prepared and used as raw materials for medicine, rubber, man-made fiber and papermaking.
