What is Calcium Carbonate?
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, produced by the sedimentation of the shells of small fossilized snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical ...

Joyce, in Encyclopedia of Forest Sciences, 2004 Calcium Carbonate. Naturally ground calcium carbonate (GCC) is produced from chalk, limestone, or marble by either a wet or dry grinding process. The basic mineral of both chalk and marble is calcite, whose crystals are rhombic in structure. A rhombic structure is best described as a cube, which unlike the platelets of clay, do not produce ...

In either case, the process must be carefully controlled since carbon dioxide can react with calcium carbonate and draw it back into solution as calcium bicarbonate, negating the softening process. Alternatively, recarbonation can be achieved through the addition of acids such as sulfuric or hydrochloric acids or through polyphosphate addition.
