Calcium carbonate (CaCO3) comprises more than 4% of the earth's crust and is found worldwide. Its most common natural forms are chalk, limestone, and marble (produced by the sedimentation of small fossilized shellfish, snails, and coral over millions of years). Chalk occurs as a microcrystalline material and has been use…
