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.
