CalcinationWikipedia

An oven for calcination of limestone The process of calcination derives its name from the Latin calcinare (to burn lime) [3] due to its most common application, the decomposition of calcium carbonate ( limestone ) to calcium oxide ( lime ) and carbon dioxide , in order to create cement .

Calcination of Limestone |

Calcination of Limestone . Calcination or calcining is a thermal treatment process to bring about a thermal decomposition. The process takes place below the melting point of the product. The name calcination is derived from the Latin word ‘Calcinare’ which mean to burn lime. Limestone is a naturally occurring mineral.
