The root of the word calcination refers to its most prominent use, which is to remove carbon from limestone through combustion to yield calcium oxide (quicklime). This calcination reaction is CaCO 3 (s) → CaO (s) + CO 2 (g). Calcium oxide is a crucial ingredient in modern cement, and is also used as a chemical flux in smelting.

In calcination, the reaction most of the time occurs at or above the thermal decomposition temperature. Calcination is derived from the Latin word calciner which translates as "to burn lime". So, calcination is mostly used in the decomposition of limestone (calcium carbonate) to lime (calcium oxide) and carbon dioxide. CaCO 3 —> CaO + CO 2

Calcination. After the limestone rocks are processed, they are transported to a lime kiln for calcination. This is the process where the limestone is heated to a temperature above 1,472ºF for decarbonation, i.e., removal of carbon dioxide in gaseous form, to produce quicklime. Almost half of the limestone's weight is lost as carbon dioxide.
