Calcination | Wiki | Everipedia

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate ( limestone) to calcium oxide ( lime) and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
