Calcium Carbonate
Calcium carbonate, or CaCO3, is found throughout the world and is one of the most commonly occurring minerals. In its natural form, it appears as chalk, limestone, and marble. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. Calcium carbonate is one of the most useful and versatile materials known to man and wet and dry grinding methods are used in processing it for industrial applications.
Applications:
Paper, Plastics, Paints, and Coatings:
Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as filler and as a coating pigment. In the paper industry, it is used as an inexpensive filler and is greatly valued for its high brightness and light scattering characteristics. In the paints industry, it is used widely used an extender and can represent as much as 30% by weight in paints. It is also one of the widest used substances in the production of master batches for the plastic industry. It also is used as a filler in adhesives, and sealants.Personal Health and Food Production:
Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. It also is found in many grocery products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine. Calcium carbonate is the active ingredient in agricultural lime, and is used in animal feed as well as water and waste treatment.Building Materials and Construction:
Calcium carbonate is used both as a building material in the form of marble and as an ingredient of cement. It contributes to the making of mortar used in bonding bricks, concrete blocks, stones, roofing shingles, rubber compounds, and tiles. Calcium carbonate decomposes to form carbon dioxide and lime, an important material in making steel, glass, and paper. Because of its antacid properties, calcium carbonate is used in industrial settings to neutralize acidic conditions in both soil and water.Mining:
Calcium carbonate in one of the most commonly found minerals in nature and is available all over the world. Pakistan is no exception and has been blessed with huge quantities of Calcium carbonate. As with other minerals, due to its geological topography, the calcium carbonate deposits in Pakistan are of very high quality, purity and whiteness. We have control over large calcium carbonate deposits and depending upon our clients’ specifications, we can deliver upto 99.5% pure calcium carbonate with whiteness also ranging between 93% – 95%, hence making it one of the best materials available anywhere in the world.Processing:
