    Dolomite is mainly composed of calcium carbonate and magnesium carbonate, as an important resource on earth, dolomite can be divided into iron dolomite and manganese dolomite, bubble will slowly comes out when meet with cold dilute hydrochloric acid. Some orange-red shade made of dolomite in the cathode-ray irradiation. With the development of modern science and technology, dolomite can be non-metallic mineral resources which can be various developed and utilized, to become a great economic value of non-metallic mineral resources.

    1. Magnesium smelting industry: ore particle size of 30120mm dolomite is an important raw material for the production of magnesium metal. Currently in China, the smelting of metallic magnesium generally used silicon thermal reduction method, magnesium yield level is consistent with the activity level of calcined dolomite.

    2. The blast furnace clogging material: if 030mm dolomite burning white as steel-making blast furnace clogging material, selling price is around 1000 yuan/t, with a good prospect.

    3. The production of Magnesium carbonate: magnesium production requirements dolomite chemical composition as follows: MgO>18CaO>29SiO2<4 pairs of K2ONa2O, no determination of acid insoluble content requirements.

    4. The production of Magnesia: New technology to extract magnesium oxide from dolomite is circulation method. Further, dolomite as the main raw material for preparing special magnesium oxide silicon steel production technology and methods have also been developed.

   5. Production of magnesium sulfate: the use of dolomite to preparation magnesium sulfate. By-products can be obtained simultaneously of CaSO4 H2O can be obtained not only magnesium sulfate (MgSO4 7H2O) crystals.

   6. Production of magnesium hydroxide: Available to get through ammonation dolomite or by acid decomposition.

   7. Production of glass: dolomite and limestone are the third largest component except for silica sand and soda ash in glass raw. With the intreoduction of dolomite magnsia method can further reduce costs, improve the chemical stability and mechanical strength of the products.

    8. Ceramics: blank and glaze used in dolomite which can reduces blank firing temperature, promote the dissolution of quartz and mullite formation.

    9. The field of environmental protection: dolomite powder can be used to improve coal mine dust flying, as filters for water treatment;

    Guilin Hong Cheng is a professional manufacturer of mill equipment modernization large enterprises, excellent product quality and perfect caring service made Hong Cheng grinding mill truly enjoy a good reputation both domestic and overseas, in infrastructure construction, mineral processing, solid waste recycling, energy conservation emission reduction, environmental protection, metallurgy, building materials, chemicals, electric power, we has thousands of production line, not only can rationally use of non-metallic mineral resources, but also can process product fineness to meet customer demand according to market requirements, achieved many support and trust from powder making enterprise.
