Industrial uses of calcium carbonate

Calcium carbonate is the trade name of limestone, a valuable resource with a wide range of uses as a mineral raw material. In the history of human civilization, limestone has been widely used because of its wide distribution in nature and easy access. As an important building material, it has a long history of mining. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide, and is an indispensable flux limestone in the metallurgical industry. After ultra-fine grinding, high-quality limestone is widely used. It is used in the manufacture of paper, rubber, paint, coating, medicine, cosmetics, feed, sealing, bonding, polishing and other products. According to incomplete statistics, the ratio of limestone consumed in cement production to building stone, lime production, metallurgical flux, and limestone consumed by ultrafine calcium carbonate is 1:3. Limestone is a non-renewable resource. With the continuous progress of science and technology and the development of nanotechnology, the application field of limestone will be further expanded.
