Ground calcium carbonate, commonly referred to as GCC, is primarily based on limestone and chalk in the UK, though marble stone is imported and processed at a few locations. Precipitated Calcium Carbonate (PCC) is produced through a recarbonisation process or as a by-product of some bulk chemical processes.

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.
