Liaoning Heavy Calcium Powder, Haicheng Heavy Calcium Powder, High-purity Calcium Carbonate Powder, Liaoning Calcium Carbonate Powder, Haicheng Calcium Carbonate Powder, Ultra-fine Calcium Carbonate Powder

Calcium carbonate is produced by processing bauxite ore through beneficiation, coarse crushing, medium crushing, grinding, grading, and packaging. It is used in the chemical industry for manufacturing magnesium, calcium magnesium phosphate fertilizer, light magnesium carbonate, granular fertilizer, as a filler in rubber and pharmaceuticals, and as an acid neutralizer for soil. It can also be used as a metallurgical flux, construction stone, refractory material, and as an ingredient in ceramics and glass. It can also be refined into magnesium metal. It is a widely used inorganic filler material, serving as an excellent performance enhancer and is extensively used in: putty powder, white paint, paint, plastics, rubber, papermaking, coatings, feed, daily chemical products, glass, ceramics, wastewater treatment, and steel mill desulfurization fields.
