Calcium carbonate for paper and board
Chalk is usually fine-textured and varies in colour from deposit to deposit. Marble gives products of the highest brightness and lowest yellowness. Precipitated Calcium Carbonate (PCC) is produced through a chemical reaction process that utilizes calcium oxide (quicklime), water and carbon dioxide to produce very pure calcium carbonate crystals.

Recovery and carbonation of of calcium in waste concrete …
Waste cement refers to the fine fraction recovered during the recycling of waste concrete as a coarse aggregate. It disproportionately contains the calcium silicate hydrate (3CaO·2SiO 2 ·3H 2 O) and calcium hydroxide (Ca(OH) 2) associated with cement, which both directly carbonate to calcium carbonate (CaCO 3) (Iizuka, 2006).
