Precipitated Calcium Carbonate (PCC) is produced from limestone using a sedimentation (precipitation) process. Industrially, PCC is made by hydrating high-calcium quicklime and then reacting the resulting slurry, or “milk-of-lime”, with carbon dioxide as per the equation: Ca(OH)2 + CO2 ? CaCO3 + H2O In theory, Calcium Carbonate contain 56% of Calcium Oxide (CaO) and 44% of Carbon Dioxide (CO2).
