Calcium carbonate provides organisms with material to grow shells and skeletons. For example, eggshells are mostly comprised of calcium carbonate. Calcium carbonate is involved in cave formation. Stalagmites and stalactites are formed due to calcium carbonate reacting with acids.
Precipitated Calcium Carbonate (PCC) PCC stands for precipitated calcium carbonate. It is a manufactured form of calcium carbonate produced under exacting conditions in order to obtain crystals of the proper shape, size and physical characteristics required for a host of complex applications.
· The solubility of calcium carbonate is about 0.05-0.07% mg/ml at room temperature. The pH of a 10% dispersion of calcium carbonate in water (saturated solution) is about 9.0. The solubility of calcium carbonate is increased by an increase in carbon dioxide solubilized in the water.

(Calcium Carbonate – CaCO3 (lime stone) and it falls out to the bottom of the container.
Reactions between acids and bases: There are several reactions in the iron and steel making processes which involve acids and bases.One of the raw materials which is fed into the Blast Furnace is limestone, an almost pure form of calcium carbonate. Limestone decomposes in the hot furnace to give calcium oxide, which is a base.
The most commonly used abrasives are hydrated silica (softened silica), calcium carbonate (also known as chalk), and sodium bicarbonate (baking soda). Other abrasives include dibasic calcium phosphate, calcium sulfate, tricalcium phosphate, and sodium metaphosphate hydrated alumina.
The pregnant solution that contained calcium ions was subsequently used to produce PCC by introducing CO 2 gas into the pregnant solution. The process is known as carbonation. The PCC was then used as fillers in paper making. The production of PCC by using calcium hydroxide as starting material was also carried out for comparison purposes. Based

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 . Precipitated Calcium Carbonate (PCC) – Minerals.
Today we consider the chemistry of calcium carbonate, the main component of limestone rocks. Actually, limestone usually contains a mixture of calcium carbonate and magnesium carbonate, which is called dolomitic limestone. For today, however, we will ignore that fact and assume our limestone contains only calcium carbonate.

Sodium carbonate (Na 2 CO 3) is found naturally or is manufactured from natural salt i.e., sodium chloride (common salt).It has many uses but, one of the major notable applications is in making of glass. Soda ash is a key chemical for producing soap, paper making, baking soda production, and bleaching fabrics and paper.
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.
Precipitated calcium carbonate is the form of CaCO3 which is manufactured by chemical reactions and the process is known as carbonation process. PCC improve the drawback of GCC, it is provide better gloss and opacity properties for the paper.
