Precipitated Calcium Carbonate
The precipitated calcium carbonate production process consists of decarbonating limestone, which separates the CaO (calcium oxide) and CO 2 (carbon dioxide). Precipitated calcium carbonate is produced by slaking high-calcium quicklime to create a calcium hydroxide lime slurry, (Ca(OH) 2 ), that is then combined with captured carbon dioxide (CO 2 ).
