Ground calcium carbonate commonly referred to as GCC is widely used as an industrial mineral. Three primary attributes particle size color and chemical purity define the quality of the GCC and define the suitability of use for any given application. Specialty Minerals Limestone Products
Calcium carbonate limestone is heated to form calcium oxide quicklime and carbon dioxide It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.
Production Process. Steps of production reactions and physical conditions are discussed in this section. Calcium carbonate decomposition CaCO 3 CaO CO 2. Calcium carbonate is heated into higher temperature and take calcium oxide CaO. CaCO 3 decomposes into CaO and CO 2 above 825 0 C. Calcium oxide and coke reaction CaO C CaC 2 CO
