Guilin Hengda HD series high efficiency Raymond mill are widely used in the field of non-metallic mineral deep processing. Recently, many people have consulted Dolomite Raymond Mill. We will analyze the processing and utilization of dolomite.
Dolomite is an important calcium and magnesium resource with a Mohs hardness of 3.5-4. Dolomite mines often contain impurities such as calcite, clay minerals, vermiculite, magnesite, and sometimes contain gypsum, anhydrite, lapis lazuli, barite, pyrite, and organic matter. Dolomite is widely used, mainly in the following aspects.
Metallurgical industry. First of all, dolomite with a ore size of 30-120mm is an important raw material for the production of metallic magnesium. At the same time, dolomite is also one of the important raw materials for alkaline refractories. Its importance is second only to magnesite, mainly used for steelmaking. It’s mainly used for furnace lining, open hearth furnace, electric furnace wall, and also used for thermal equipment such as refining equipment outside the furnace and cement kiln.
Chemical Industry. Dolomite is processed in the chemical industry to produce magnesium carbonate. At the same time, dolomite can be also produce important chemical raw materials such as magnesium sulfate, magnesium oxide and magnesium hydroxide after processing.
Building materials industry. The manufacture of magnesium oxychloride cement is another important use of dolomite. In addition, after calcining dolomite to form caustic dolomite, it can be also processed into magnesium hydroxide cement and magnesium sulfate cement. At the same time, the processing and utilization of dolomite also involves fields such as glass and ceramics.
With the development of the magnesium smelting industry, more and more tailings slag occupies the cultivated land, increases the environmental load, and uses the dolomite to smelt the metal magnesium after the tailings to produce magnesium-potassium multi-component fertilizer. In addition, dolomite can be used instead of serpentine to produce calcium magnesium phosphate fertilizer.
