Text SolutionText solutionverified iconVerified

Calcination is one of the pyrometallurgical process, like roasting by which a concentrated ore gets converted into its oxide.
In calcination, a hydrated carbonate or bicarbonate ore or a hydrated ore is heated at lower temperature (compared to roasting) in absence of air to give its oxide as in options (a), (b) and (c). Here, volatile non-metallic oxides like , , are also produced.
Roasting is valid mainly for sulphide ores like option (d), where gets liberated. In this reaction, calcination cannot be used.
