AzaanSaifi:
Because the primary use of magnesium carbonate is the production of magnesium oxide by calcining. Magnesite and dolomite mineralsare used to produce refractory bricks.MgCO3 is also used in flooring, fireproofing, fire extinguishing compositions, cosmetics, dusting powder, and toothpaste. Other applications are as filler material, smoke suppressant in plastics, a reinforcing agent in neoprene rubber, a drying agent, a laxative to loosen the bowels, and color retention in foods.
