Precipitated Calcium Carbonate - Manufacturing Plant ...

The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals. Precipitated calcium carbonate (PCC), a manufactured form of calcium carbonate, is made by first hydrating high-calcium quicklime, and then reacting the resulting slurry or milk oflime with carbon dioxide.

Umic

The produced slaked lime then carbonated to precipitate Calcium Carbonate [Ca(OH)2 + CO2 => CaCO3 + H2O]. The precipitated calcium carbonate (PCC), which is free of impurities, is then filtered in a belt filter followed by drying in a flash dryer. The dried calcium carbonate is then fine milled to the required particle size.

Current precipitated calcium carbonate production methods rely heavily on the use of fossil fuels to form the initial calcium oxide. The burning of such fuels results in the release of large volumes of green house gases including carbon dioxide. CalcifEXE aims to produce PCC without the need for fuels.
