Answer:
Calcination is defined as the process of converting ore into an oxide by heating it strongly. The ore is heated below its melting point either in the absence in the air or in limited supply. This method is commonly used for converting carbonates and hydroxides to their respective oxides.
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.
