Calcium Carbonate. Calcium carbonate is one of the most abundant minerals and is the main constituent of limestone. Most calcium carbonate occurs as limestone, however, heat and pressure can result in the metamorphic form, marble. Calcium carbonate is generally mined as limestone or marble depending on application.

Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used; arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.
Mine high purity calcium carbonate rock. Crush the rocks to the particle size needed for processing – small stones or powder. Separate some of the impurities from the crushed rock. 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 ...

The calcium cycle is a transfer of calcium between dissolved and solid phases. There is a continuous supply of calcium ions into waterways from rocks, organisms, and soils. Calcium ions are consumed and removed from aqueous environments as they react to form insoluble structures such as calcium carbonate and calcium silicate, which can deposit to form sediments or the exoskeletons of organisms.
