| Physical and Chemical Properties | Dolomite is a kind of carbonate rock with dolomite as the main mineral component, and its color is white or light grayish white. Often mixed with calcite, clay minerals, magnesite, gypsum and other impurities. Ores are generally fine-grained or medium-grained structures, layered, massive, breccia or gravel-like structures. Dolomite belongs to the tripartite crystal system. The crystals are often saddle-like rhombohedrons, and the aggregates are often granular or massive. The color is colorless, white or light brown to dark brown. Glass luster. Hardness 3.5~4, density 2.8~2.9g/cm3. Insoluble in water. When calcined to 700~900 ℃, carbon dioxide is lost and becomes a mixture of calcium oxide and magnesium oxide, which is called caustic dolomite. When the calcination temperature reaches 1500 ℃, magnesium oxide becomes periclase and calcium oxide becomes α-CaO. Dolomite is one of the minerals widely awarded in sedimentary rocks. |

| usage | dolomite powder is limited in dosage in paint, limited to being used as filler, mainly playing the role of white pigment. However, due to the coarse particles, the refractive index is similar to the solvent of the coating, and the hiding power is weak. There is no special effect in the application, but it is only used as a physical pigment filling coating. Dolomite is used in the chemical industry to make magnesium sulfate, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular chemical fertilizer, filler for rubber and medicine, and neutralizer for soil acidity. It can also be used as an ingredient for metallurgical fluxes, building stones, refractory materials, ceramics and glass. Metallic magnesium can also be extracted.

| production method | dolomite ore is generally mined by open pit, and the process flow is shown in "phosphorite". Generally, mineral processing is not required, and ore washing is required when the silt content is large. dolomite ore is processed by beneficiation, coarse crushing, medium crushing, grinding, grading and packaging to obtain dolomite powder. |
