Dolomite sand 40-80 mesh

Dolomite is a carbonate mineral, there are iron dolomite and manganese dolomite respectively. Its crystal structure resembles calcite, and it is often rhombohedral. It will slowly bubble when exposed to cold dilute hydrochloric acid. Some dolomite emits orange-red light under cathode ray irradiation. Dolomite is the main mineral component of dolomite and dolomitic limestone. Dolomite can be used in building materials, ceramics, glass and refractory materials, chemical and agricultural, environmental protection, energy saving and other fields. Mainly used as a flux for alkaline refractories and blast furnace ironmaking; production of calcium-magnesium-phosphate fertilizers and production of magnesium sulfate; and ingredients for the production of glass and ceramics. dolomite sand

Dolomite series products of various quality: dolomite ore, dolomite sand 6-10 mesh, 10-20 mesh, 20-40 mesh, 40-80 mesh, 80-120 mesh, dolomite powder 10 mesh through, dolomite super Fine powder 140 mesh, 325 mesh, 600 mesh, 1000 mesh, 1600 mesh.

When the dolomite is heated to 700~900℃, it decomposes into a mixture of carbon dioxide, calcium oxide and magnesium oxide, called caustic magnesite, which is easy to react with water. When dolomite is calcined at 1500℃, magnesia becomes periclase, calcium oxide transforms into crystalline a-CaO, with compact structure, strong water resistance, and refractoriness up to 2300℃.

The dolomite deposits in my country are distributed in the carbonate rock series. The older the strata, the more deposits, and most of them are concentrated in the bottom of the Sinian system. For example, the Liaohe Group in Northeast China, the Sangzi Group in Inner Mongolia, and the Jianou Group in Fujian all have dolomite deposits. Secondly, the dolomite deposits in the Sinian and Cambrian systems are also relatively extensive, such as the Liaodong Peninsula, Jidong, Inner Mongolia, Shanxi, Jiangsu and other places are also produced by large deposits. Carboniferous and Permian dolomite deposits are mostly distributed in Hubei, Hunan, Guangxi, Guizhou and other places.

my country is rich in dolomite deposits, and the proven reserves of dolomite sand can meet the needs of economic construction. Most of the deposits have been developed and utilized, and their origins are all over the provinces. Among them, Kazuo County, Chaoyang City has the most output.
