Dolomite Powder Chinese Name: Dolomite powder Synonyms: Dolomite; C.I. CAS No.: 7000-29-5; Molecular Formula: C2CaMgO6; Molecular Weight: 184.4008; EINECS No.: 230-274-9; Related Categories: Chemical mineral raw materials; Inorganic chemical products; Plant extracts; Pigments; Raw materials. Dolomite ore is processed through beneficiation, coarse crushing, medium crushing, powdering, grading, and packaging to produce dolomite powder. Dolomite is used in the chemical industry to manufacture magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, as a filler in rubber and pharmaceuticals, and as a soil acidity neutralizer. It is also used as a metallurgical flux, construction stone, refractory material, and as an ingredient in ceramics and glass. Metal magnesium can also be extracted from it. It is a widely used inorganic filling material. It is an excellent performance enhancer and is widely used in: putty powder, white paint, paint, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields.
