Dolomite Powder Chinese Name: Dolomite Powder Synonyms: Dolomitic Limestone C.I. CAS No.: 7000-29-5 Molecular Formula: C2CaMgO6 Molecular Weight: 184.4008 EINECS No.: 230-274-9 Categories: Chemical Mineral Raw Materials; Inorganic Chemical Products; Plant Extracts; Pigments; Raw Materials Dolomite ore is processed through beneficiation, coarse crushing, medium crushing, pulverization, grading, and packaging to produce dolomite powder. Dolomitic limestone is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizers, light magnesium carbonate, granular fertilizers, and as a filler in rubber and pharmaceuticals, as a neutralizer for soil acidity. It can also be used as a metallurgical flux, building stone, refractory material, and as an ingredient in ceramics and glass. It can also be used to extract magnesium metal. It is a widely used inorganic filling material, also serving as an excellent performance enhancer. It is extensively used in: spackle, white paint, paints, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields.
