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 known as slaking This slurry is then cooled and transported to a mix tank, where CO 2 is added. This carbonates the calcium hydroxide slurry to produce calcium carbonate.
