Data for the annual production of calcium carbonate are not readily available. Approximately 1 billion tonnes of its two principal ores, limestone and dolomite, are mined annually in the US. Given the relative amounts of lime that is used in different countries, an estimate of worldwide mining of calcium carbonate is 15 billion tonnes a year.
Lime is a calciumcontaining inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium is also the name for calcium oxide which occurs as a product of coalseam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.
Limestone is quarried in Britain as either large blocks that are used for building, or in small pieces the size of sand or gravel, which are used for industrial purposes.. When limestone is crushed into powder, it is sometimes referred to by its chemical name, calcium carbonate, or its chemical symbol, CaCO and CaCO 3 are therefore the same material, but used in different ways ...

Lime calcining is the conversion of limestone (CaCO3) to lime (CaO). Limestone is a sedimentary rock, the third most abundant mineral. Limestone is mostly quarried above ground; however, some underground limestone mining is done. Limestone is found with many different characteristics and different impurities.
In the mining industry, lime products are used to refine and condition metal ores and nonferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel and Zinc and are used in Gold and Silver processing to ensure proper pH in the leaching circuit.

Uses. The largest use of lime is in steel manufacturing where lime is used as a flux to remove impurities such as phosphorus and sulfur. Lime is used in power plant smokestacks to remove sulfur from the emissions. Lime is also used in mining, paper and paper pulp production, water treatment and purification, and in wastewater treatment.
The lime cycle consists of first burning of limestone to form quicklime. Hydrated lime can then be produced by adding water to the quicklime. At this point, carbon dioxide in the atmosphere or from industrial processes react with hydrated lime to convert it back to limestone. This cycle is called the lime .
