Abstract
The invention discloses a production method of common light calcium carbonate, and belongs to the field of a production method of calcium carbonate. In a production process, limestone is taken as a main raw material, and requirements on auxiliary raw materials of water and fuel are higher; the limestone and the fuel are calcined to obtain lime and carbon dioxide, a digestion reaction is performed on the lime and the water to obtain calcium hydroxide emulsion, and a carbonization reaction is performed on the carbon dioxide and the calcium hydroxide emulsion to obtain the light calcium carbonate. According to the production method, the problem that the particle size and the viscosity of a product in the production process are difficult in control can be solved, continuous production can be realized by using conventional equipment, the product is good and stable in quality, and the whiteness of the calcium carbonate produced by the production method reaches 95-97 degrees.
