Calcination of Limestone | ispatguru.com

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.

23 Thermal decomposition of calcium carbonate Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.
