Precipitated Calcium Carbonate (PCC)—also known as purified, refined or synthetic calcium carbonate. Precipitated calcium carbonate (PCC), is made by first hydrating high-calcium quicklime, and then reacting the resulting slurry or "milk-of lime" with carbon dioxide. The resulting product is extremely white and has a uniformly small particle size. It has numerous uses, most notably in the paper industry. With the trend in papermaking towards using the alkaline over the acid process, PCC is being used increasingly as a filler and coating pigment for premium quality paper. The trend is to produce PCC in slurry form at satellite plants located near the paper mills, using commercial quicklime, although it is also produced and sold commercially. PCC is used to enhance the brightness, color, smoothness, and bulk of the paper, replacing more expensive paper pulp. Approximately 75% of worldwide PCC production is used for this purpose. Calcium carbonates, including PCC, are considered to be non-toxic. As long as the PCC meets certain purity requirements, it can be used as a direct food additive, as a pharmaceutical or as an indirect additive in paper products that come in contact with food. Uses • PCC is used to enhance the brightness, color, smoothness, and bulk of the paper, replacing more expensive paper pulp. • PCC is also used extensively as a plastics additive, white paint pigment, putty, ingredient in sealers and adhesives, and specialized filler. • It is also an important ingredient in toothpaste. • Calcium carbonate is also used in the purification of iron from iron ore in a blast furnace. The carbonate is calcined in situ to give calcium oxide, which forms a slag with various impurities present, and separates from the purified iron. • Precipitated calcium carbonate (PCC), pre-dispersed in slurry form, is a common filler material for latex gloves. • Pharmaceutical Industries use precipitated Calcium Carbonate in the fermentation process and to manufacture tapped density tablet making. It is used to neutralize the acids in fermentation process and for calcium supplement tablets. • Detergent powder manufacturers due to its characteristics of high water absorption capacity and fluffiness as this makes the powder free flowing and fluffiness makes it look bigger pack. • Precipitated Calcium Carbonate is used by rubber product manufacturers for the manufacturing of different rubber products like Tyres, Tubes, Hawai Chappals, Soles, Straps and other rubber parts. • The chewing gum manufacturers uses it as a calcium supplement as a mold release material where as powder drinks manufacturers uses it to neutralize excess acid in the food. The Wine manufacturers use Precipitated Calcium Carbonate as a filtration aid. Market Survey Worldwide, almost 10 million tons of precipitated calcium carbonate (PCC) is produced annually for use in a wide range of end use applications. Roughly 70% of the total is consumed by the paper industry for the filling and coating of paper. Large amounts of PCC are also used in the filling of polymers, as a pigment in paint, and as a thixotrope in sealant and plastisol formulations. ? The largest market for precipitated calcium carbonate (PCC) in the United States is the paper industry, where it is used predominantly as a filler. In 2010, approximately 90% of the PCC produced was consumed by the paper industry. Growth was attributed to the paper industry's conversion from acid papermaking technology to alkaline and to the success of the PCC on-site satellite plant concept where producers supply product from plants located adjacent to paper mills. The paper industry is the largest consumer of PCC. Using an estimated 5.5 MT, this market accounted for over 40% of world PCC consumption. The traditional use for PCC in paper has been as filler, but demands for coating grades including blends of PCC and GCC, is increasing. Plastics are the second largest market for PCC. Consumption worldwide in this market totaled 3.5Mt. Asia dominates consumption, accounting for some 85% of the world total. The largest market for precipitated calcium carbonate (PCC) in the United States is the paper industry, where it is used predominantly as filler. Forecast growth in Chinese PCC consumption reflects rising domestic demand for paper, for paints and plastics in the construction industry, and for rubber. Chinese PCC consumption is forecast to rise by 6%py to reach 13Mt in 2014. Few Major Companies names are listed below: Dewan Rubber Inds. Ltd. Genus Prime Infra Ltd. Thirani Chemicals Ltd.
