Calcination | chemical process | Britannica.com

Calcination: Calcination, the heating of solids to a high temperature for the purpose of removing volatile substances, oxidizing a portion of mass, or rendering them friable. Calcination, therefore, is sometimes considered a process of purification. A typical example is the manufacture of lime from limestone.

Calcination - an overview | ScienceDirect Topics

Calcination of limestone takes places essentially at about 1000 °C. The reaction is highly endothermic and consumes large amount of thermal energy (1.1.26) that comes from the burning of coke. Furthermore, limestone decomposition releases CO 2 gas, and the CO 2 gas will react further with coke through Boudouard reaction (1.1.27), leading to extra solution loss of carbon.
