Dolomite chemical composition of Ca Mg (CO3)2, crystal of trigonal system carbonate minerals. Crystal structure and similar to that of calcite dolomite, crystal shape as the rhombohedron, crystal bending into the saddle, often polysynthetic twin common, more massive, granular aggregate. Pure white marble is white, sometimes because it contains other elements and impurities in grey color, such as green, sallowness, pink glass luster. Three groups of rhombohedron cleaves completely, brittle. 3.5-4 mohs hardness, specific gravity 2.8-2.9. Slow cold mineral powder in dilute hydrochloric acid.
Dolomite is a carbonate mineral, respectively with manganese iron dolomite and dolomite. Its crystal structure like calcite, often assumes the rhombohedron. Slowly out of the bubble when encounter cold dilute hydrochloric acid. Some dolomite in cathode ray irradiation was orange light. Dolomite is composed of dolomite and dolomitic limestone of the main mineral composition. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical industry and agriculture, environmental protection, energy saving, etc. Mainly used as basic refractory and blast furnace ironmaking flux; Preparing calcium-magnesia phosphate fertilizer production and magnesium sulfate; As well as the production of glass and ceramics ingredients.
Quality dolomite series products: dolomite ore, dolomite sand 6-10 orders, 10-20, 20 to 40, 40-80 mesh, 80-120 mesh, 10 mesh by dolomite fines, ultrafine dolomite powder, 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh.
Dolomite heating to 700 ~ 900 ℃ is decomposed into carbon dioxide and a mixture of calcium oxide and magnesium oxide, said caustic magnesium marble, easy to react with water. When the cloud of writing 1500 ℃ calcination, magnesium oxide become periclase, a - CaO CaO into crystals, compact structure, strong water resistance and refractoriness is as high as 2300 ℃.
