Calcination chemical process Britannica

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.
