Precipitated Calcium Carbonate (PCC) - Manufacturing Process

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.
