How is calcium carbonate made?
How Is Precipitated Calcium Carbonate (PCC) Made?#N#Almost all PCC is made by direct carbonation of hydrated lime, known as the milk of lime process. The milk of lime process is simple in concept: 1 Mine high purity calcium carbonate rock. 2 Crush the rocks to the particle size needed for processing – small stones or powder. 3 Separate some of the impurities from the crushed rock. 4 Calcine (heat) in a kiln to 1850° F, which takes the calcium carbonate apart, forming lime (CaO) and carbon dioxide gas (CO2). The carbon dioxide can be captured for reuse. CaCO3 + Heat → CaO + CO2 ↑ 5 Add the lime to water to form calcium hydroxide (hydrated lime or slake).#N#CaO + H2O → Ca (OH)2 6 Separate out additional impurities from the slaked lime. 7 Combine the captured carbon dioxide with the slaked lime. Calcium carbonate reforms, and since it is insoluble in water, precipitates out.#N#Ca (OH)2 + CO2 → CaCO3 ↓ + H2O 8 Separate additional impurities and grit from the PCC slurry. 9 If the PCC is to be used in a paper mill or shipped to a latex paint plant, the lower solids slurry may be used as is, or processed to bring up the solids level, then tested before transfer or shipment. 10 If the PCC is to be used as a dry product, the slurry is dewatered, dried, milled, packaged and tested.
