Calcium Carbonate CaCO3 is the generic name for a variety of different minerals found all over the world. It's found in the shells of marine animals and is an active component in agricultural lime. It's a component of lime stone, marble, chalk, gypsum and precipitated chalk. Calcium carbonate ores can be found in two of the three major types of rocks: sedimentary and metamorphic. Sedimentary rocks form from sediment or from transported fragments deposited in water. Limestone, for example, is formed from inorganic remains, such as shells and skeletons. Metamorphic rocks such as marble, slate, quartzite form when a rock mass is subjected to great heat and pressure. The ore may contain other elements like magnesium, iron and manganese that affect whiteness, hardness and specific gravity.

Calcium carbonate is used in many aspects of life, either in naturally occurring state or pure form. Pure calcium carbonate is extracted from natural sources by means of various techniques like mining and quarrying.
Pure calcium carbonate (e.g. for food or pharmaceutical use), can be produced from a pure quarried source (usually marble).

We supply ground and Precipitated Calcium Carbonate..

Precipitated calcium carbonate (PCC) is an innovative product, derived from lime, which has many industrial applications. PCC is made by hydrating high-calcium quicklime, and then reacting the resulting slurry, or “milk-of-lime”, with carbon dioxide. The resulting product is extremely white and typically has a uniform narrow particle size distribution. PCC is available in numerous crystal morphologies and sizes, which can be tailored to optimize performance in a specific application.


Iron Steel:-Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace. The carbonate is calcinedin situto give calcium oxide, which forms a slag with various impurities present, and separates from the purified iron.

Oil Industry:-In the oil industry, calcium carbonate is added to drilling fluids as a formation-bridging and filtercake-sealing agent; it is also a weighting material which increases the density of drilling fluids to control the downhole pressure.

Paper Industry:-GCC or PCC is used as a filler in paper because they are cheaper than wood fiber. Printing and writing paper can contain 10–20% calcium carbonate. In North America, calcium carbonate has begun to replace kaolin in the production of glossy paper. Europe has been practicing this as alkaline papermaking or acid-free papermaking for some decades. PCC has a very fine and controlled particle size, on the order of 2 micrometres in diameter, useful in coatings for paper.

Paints:-Calcium carbonate is widely used as an extender in paints, in particular matte emulsion paint where typically 30% by weight of the paint is either chalk or marble.

Plastics:- It is also as a popular filler in plastics.Some typical examples include around 15 to 20% loading of chalk in unplasticized polyvinyl chloride (uPVC) drain pipe, 5 to 15% loading of stearate coated chalk or marble in uPVC window profile. PVC cables can use calcium carbonate at loadings of up to 70 phr (parts per hundred parts of resin) to improve mechanical properties (tensile strength and elongation) and electrical properties (volume resistivity). Polypropylene compounds are often filled with calcium carbonate to increase rigidity, a requirement that becomes important at high use temperatures.Here the percentage is often 20–40%.


In ceramics/glazing applications, calcium carbonate is known aswhiting, and is a common ingredient for many glazes in its white powdered form. When a glaze containing this material is fired in a kiln, the whiting acts as a flux material in the glaze. Ceramic tile adhesives typically contain 70 to 80% limestone.

An important use of calcium carbonate is in the building industry. Due to its wide abundance and properties, it has been used as a building substance since ancient times. For example, the Egyptians used limestone for building their pyramids. Another notable monument made up of white marble is the Taj Mahal in India. Today, calcium carbonate is used in construction of buildings, roads and other engineering works.
As calcium supplement:-
Since calcium is essential for healthy bones and teeth, calcium carbonate is used as dietary calcium supplement. Calcium carbonate supplement is effective to treat certain ailments related to calcium deficiency, for example, osteoporosis and acidity problems. Calcium supplements, made from calcium carbonate, are prescribed in various doses as per the requirement of the patients. Calcium carbonate is used in homeopathy, production of toothpaste and as an inert substance in tablets.

Calcium carbonate is added to a wide range of trade and do it yourself adhesives, sealants, and decorating fillers.

Decorating crack fillers contain similar levels of marble or dolomite. It is also mixed with putty in setting stained glass windows, and as a resist to prevent glass from sticking to kiln shelves when firing glazes and paints at high temperature.
