Calcination is the heating of an ore at high temperature. Calcium carbonate undergoes calcination to give calcium oxide. Calcium oxide doesn't undergo calcination.

Calcination is to be distinguished from roasting, in which more complex gas-solid reactions take place between the furnace atmosphere and the solids. Although calcination can only be endothermic roasting can also be exothermic.

CALCINATION

This is a process in which corbon is expelled from its compound i.e cao.

ROASTING

This is a process in which metal is converted in to its oxide

calcination

Calcination is applied to an ore because for the extraction of carbon from an ore.Mostly the ore is consist of carbon and we can easily provide carbon from it.

Calcination is generally applied to an ore because of our daily use.Iknow that my given answer is wrong but please accept it i will be thankfull to you people.
