The Precipitated Calcium Carbonate Production Process. Modern PCC production utilizes the milk of lime process, which involves direct carbonation of hydrated lime slurry. The PCC production process begins with quicklime (CaO). The quicklime is mixed with water to form a calcium hydroxide slurry (Ca (OH) 2) in an exothermal chemical reaction
