CALCINATION

Calcination is a term used in metallurgy to denote the operation of roasting or burning ores. The process varies according to the nature of the ore, and may have the objective to expel certain volatile constituents such as sulphur or arsenic, or to produce an oxide by exposing the heated ore to air. Chalk is calcined to expel the carbon dioxide and produce quicklime.
