Calcium carbonate, as it is used for industrial purposes, is extracted by mining or quarrying. Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. In the later case calcium carbonate is derived from the mixture, forming a grade of product called "Precipitated Calcium Carbonate,” or PCC. PCC has a very fine and controlled particle size, on the order of 2 microns in diameter, particularly useful in many different industries. The other primary type of industrial product is "Ground Calcium Carbonate,” or GCC. GCC, as the name implies, involves crushing and processing limestone to create a powdery-like form graded by size and other properties for many different industrial and pharmaceutical applications.
Precipitated Calcium Carbonate:
PCC is made from a high purity calcium carbonate rock called limestone. Riddhi Metal and Chemicals (india) PCC Products uses high quality limestone for its pcc products. For the said project, the most accessible and best area for raw material is the deposits in Gujarat. No other place in India can compete Gujarat for limestone mines.
APPLICATIONS:
Our product the different shapes allow PCC to act as a functional additive in sealants, Toothpaste & Tooth powder, adhesives, Plastics, Rubber, Inks, Paper, Pharmaceuticals, nutritional supplements, Cosmetics, Dentifrices, Foods and Beverages, animal food and many other demanding applications. A formulator can choose a shape, and the physical properties that result from that shape, that gives the best performance in the end use.
