When magnesite is calcined at 800-1200â??, it is called "light burning", and its product is called light burning magnesium powder, which is called light burning powder for short. Light-burned powder is mainly used to make cementitious materials, heat-insulating and sound-insulating building materials and ceramic raw materials, and it is also an ideal raw material for producing high-density magnesia. After chemical treatment, light-burned magnesium can be made into a variety of magnesium salts, which are used in magnesium sulfate, light magnesium oxide, inorganic glass fiber reinforced plastic, magnesium hydroxide, fire-proof board, magnesia-alumina spinel, light-weight wallboard, greenhouse bracket, ventilation pipeline, fire-resistant cable, magnesite manhole cover, mold, trailer, and so on.

Dead burned magnesite 97% is a chemical substance, which means that when magnesite is calcined at 1800C, carbon dioxide completely escapes, and magnesium oxide forms a dense block of periclase. This dead burned magnesite has a high degree of fire resistance. Its main component is magnesia, which is made of natural special magnesite magnesia through flotation purification, light burning, fine grinding, high pressure ball pressing, and ultra high temperature oil shaft kiln calcination. Application: Dead burned magnesite 97% are made from sorted super grade natural magnesite through sections including float concentration, calcination, fine grinding, high pressure briquetting and ultra high temperature sintering in heavy oil shaft kilns. They are good quality materials for making magnesia bricks and monolithic refractories. Packing: Jumbo bag(or according to the customer requirement)
Caustic Calcined Magnesia(CCM) is made from raw magnesite through calcination in reverberatory furnace or gas suspension calciner or fluid bed furnaces. This product is featured with even calcination, stable quality, high purity, and good activity, thus is widely used as a mineral additive for animal feed production, in chemistry for fertilizers and in environmental field for elimination of acid rains impacts.

The Calcined Dolomite Powder is a result of Calcinations of Natural Dolomite Lumps. After burning, calcium oxide contains becomes 50% to 55% and Magnesium Contains 30% to 38%. Therefore, we have given it name of Dolo Lime, Calcined Dolomite or Burnt Dolomite. Calcined Dolomite Lumps have normally been formed by the replacement of some of the calcium in limestone with magnesia, a process known as dolomitisation. Theoretically, dolomitic lime should be a stoichiometric mixture of CaO and MgO, i.e. 58% CaO and 42% MgO. In practice, because of impurities and differing levels of dolomitisation, commercial products normally contain 35-40 % MgO. Calcined Dolomite Lumps are the best catalysts and base chemical for steel plants. Chemical Name : Calcium Magnesium Oxide Chemical Formula : MgO.CaO Major Applications : Iron and steel industry Non-ferrous metals Ore concentration Alumina & bauxite Gas treatment Hazardous waste treatment Animal waste treatment Packing : 50 kg bags/1000 kgs bags
Dolomite Calcium Magnesium Carbonate CaMg(CO3)2 In England, dolomite has become a useful source for the production of magnesite by reacting calcined dolomite with sea-water. Dolomite is a double carbonate of calium and magnesium, CaCO3, MgCO3. The mineral was first identified by Count Dolomien in 1791 and named after its discoverer. It is of sedimentary origin and is supposed to have been formed due to chemical action of sea-water containing high percentage of magnesia, on limestone. Theoretically, dolomite contains : CaCO3 : 54.35% MgCO3 : 45.65%
