Precipitated calcium carbonate, made by dropping calcium oxide into water, is used by itself or with additives as a white paint, known as whitewashing. Calcium carbonate is added to a wide range of trade and do it yourself adhesives, sealants, and decorating fillers. Ceramic tile adhesives typically contain 70% to 80% limestone.
Extraction of Iron. Chemistry of the blast furnace . Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates).
Calcium carbonate can also be an additive to food products for livestock animals and humans and as a supplement in vitamins. In water and sewer treatment plants, calcium carbonate is employed in the removal of acidity and impurities. Calcium Carbonate Uses. The list of uses of calcium carbonate is .

Commonly known as nitrolime, calcium cyanamide is used as fertilizer. It is hydrolysed to cyanamide, H 2 NCN. Steelmaking. Calcium carbide is used: in the desulfurization of iron (pig iron, cast iron and steel) as a fuel in steelmaking to extend the scrap ratio to liquid iron, depending on economics.
Calcium carbonate concentrates can be found in a wide variety of applications, including injection molding, blow molding and extrusion coating. This analysis, however, focuses on the use of CaC03 in high-density polyethelyne resin (HDPE), which is used in the manufacture of plastic bags and film products for flexible packaging.
Sep 04, 2014· The mineral calcite is used by the construction industries to produce cement, concrete, and manufacture of iron, steel and glass.

Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used; arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.

Calcium oxide is used to produce sodium hydroxide from sodium carbonate in chemical recovery at Kraft pulp mill. (Read also Inorganic Water Pollutants) 6. As Plaster. There is archaeological evidence that Neolithic B Pre-Pottery (pottery sticks) uses lime-based plaster for flooring and other uses.
Iron Carbonate is a water insoluble Iron source that can easily be converted to other Iron compounds, such as the oxide by heating (calcination). Carbonate compounds also give off carbon dioxide when treated with dilute acids. Iron Carbonate is generally immediately available in most volumes.
Calcium carbonate is used in the purification and separation of iron from its ore. It is often used in swimming pools for maintaining the alkalinity of water and countervailing acidic properties of the disinfectant. As it is heavy, calcium carbonate increases the density of drilling fluids and helps in controlling the down hole pressure. Hence it is widely used in the oil industry.
