Calcium carbonate, or CaCO3, comprises more than 4% of the earth's crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble. Calcium carbonate appears as white, odourless powder or colourless crystals. Calcium carbonate (CaCO3) is the most widely used filler in polymer formulations.

The Calcium Carbonate Manufacturing Process. Natural mineral sources are necessary to make commercially usable calcium carbonate. Manufacturing processes are used to improve specific properties and reduce the size of particles within the material. Calcium carbonate is mined from open pits or underground, then drilled, blasted, and crushed.
