cal·cine

C0027800 (kăl-sīn′, kăl′sīn′)v. cal·cined, cal·cin·ing, cal·cines v.tr.1. To heat (a substance) to a high temperature but below the melting or fusing point, causing loss of moisture, reduction or oxidation, and the decomposition of carbonates and other compounds.2. To convert (liquid material, especially radioactive wastes) to granular solids by drying at very high temperatures.v.intr. To be calcined.n. A substance produced by calcining.

[Middle English calcinen, from Old French calciner, from Medieval Latin calcīnāre, from Late Latin calcīna, quicklime, from Latin calx, calc-, lime; see calx.]

It is sometimes a step in the extraction of metals from ores. Calcination is distinguished from drying, in which mechanically held water is driven off by heating, and from roasting, in which a material is heated in the presence of air to oxidize impurities. Originally calcination meant the method of obtaining lime (calcium oxide) from limestone by heating it to drive off carbon dioxide.

calcination

[‚kal·sə′nā·shən] (chemical engineering) A process in which a material is heated to a temperature below its melting point to effect a thermal decomposition or a phase transition other than melting.

(kal'si-nā'shŭn), The process of calcining.

calcination

The process of heating a solid (e.g., an ore) in air below its melting point to effect thermal decomposition, phase transition or remove volatiles, thereby changing the original solid into something else—e.g., heating calcium carbonate to release CO2 gas and form calcium oxide.
