Question

what is calcination?​

Answer 1

Answer:

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.

Answer 2

Calcination is a process of heating ore in the absence of air to a high temperature but insufficient to melt the ore. Generally, carbonates and hydrated ores are calcined. Example: ZnCO3 → ZnO + CO2.
