Precipitated Calcium Carbonate (PCC) - Manufacturing Process
Precipitated Calcium Carbonate Production. Precipitated calcium carbonate is produced using the most economic process existing today. Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C. To ensure a high level of purity, the calcination process is carried out using natural gas.

May 06, 2013 · An application of a stone equilibrium for an industrial system is lime production from limestone. The products which are made from burnt limestone are called lime (ie. quicklime and hydrated lime). Limestone is naturally occurring, and it also consits of minerals in small pieces. Presently, limestone products are used as a crucial part in most industrial processes.
Calcium carbonate - Essential stone Industry
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.
