Ground Calcium Carbonate (GCC) created by nature over millions of years. Most calcium carbonate deposits are made up of the remains of marine organisms that have sedimented to the bottom of a shallow sea. These organisms, such as crustaceans, algae, and coral, absorb calcium carbonate from the water and use it to form their skeletons and shells.

1991-1-1 The kneaded carbonate promoted the gasification of all the coals examined to a large extent. The effectiveness of CaCO 3 catalyst was strongly dependent on the coal type; CaCO 3 was more effective for the coals with smaller amounts of inherent Ca,as observed with other Ca compounds like Ca(OH) 2 and Ca(CH 3 COO) 2 [2,5].

Paper, Plastics, Paints, and Coatings: Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler and due to its special white color as a coating pigment. In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper.
