Calcium carbonate is known by aragonite or limestone come with chemical formula CaCO3. It comprises 4% of the earth’s total crust and is found in egg shells, snails, mineral rocks, pearls, shells of marine organisms and so on. It is an odourless, tasteless powder used in health supplements, agricultural industry, for environmental applications and many more.
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 production of paper. 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.
The feed grade Calcium Carbonate has various applications and benefits, such as:
