Calcination - It is the process of converting an ore into its oxide by heating strongly, below its melting point either in a limited supply or in absence of air. This method is commonly used for converting carbonates and hydroxides to their respective oxides. During calcination, moisture and volatile impurities are also removed.
For example: Calcium carbonate is converted into calcium oxide by calcination.

The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.
