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 up to 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
We are proud to proclaim that we are a complete vertically integrated unit processing calcium carbonate lumps to fine and ultrafine powders or GCC. Our stare-of-the–art manufacturing plant is 100% European origin and is one of its kind in Pakistan. Equipped with the latest technology in grinding and formulation, the unit consists of ball mills, classifiers, pneumatic transportation systems, coating plant and analysers. In order to control the consistency of the product, our plant has an in-line particle size analyzer, which eliminates the need for continuous sampling and ensures that entire product batches conform to the particle size specifications down to a micron. This system is one of its kind in Pakistan and gives us a unique edge over our competitors. The facility also has a fully automatic coating unit which has also been imported from Europe and is fully compatible with the grinding plant. We can coat our material as per customers’ specifications to the smallest percentage. Depending on the grade being produced the plant has a production capacity upto 20 tons per hour. The product is currently available in 25 kg PP bags but we can pack in bulk in special cases if the order size is sufficient. Furthermore, we have the capacity to consistently produce top-cut size ranging from d98<20 microns down to d98<3.5 microns MSDS sheet Given our unique geographical location, we have an exceptional advantage to deliver our finished product all over the world at very competitive rates.
