Examples of Calcination. A common instance of calcination is the conversion of calcium carbonate to calcium oxide. CaCo3 →Δh CaO + Co C a C o 3 → Δ h C a O + C o. Here are a few more examples of calcination: Decomposition of limestone to remove carbonate ores and carbon dioxide. The removal of water of crystallisation from …

Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.
