Calcium carbonate can be divided into light calcium carbonate and heavy calcium carbonate according to different production methods. Light calcium carbonate, also known as precipitated calcium carbonate, is prepared by chemical processing; Heavy calcium carbonate, also known as ground calcium carbonate, is prepared by directly crushing natural limestone, calcite and chalk by mechanical method.
As a filler, heavy calcium can be used in papermaking, plastics, rubber, coatings, sealants and other industries.
