Vedclass · Answer

(D) Calcination is a process of heating an ore strongly in a limited supply or absence of air. It is primarily used for carbonate or hydrated ores. In the reaction $MgCO_3 \rightarrow MgO + CO_2$,magnesium carbonate is heated to release carbon dioxide,which is a classic example of calcination. Option $A$ is an oxidation reaction,option $B$ is roasting (in the presence of excess air),and option $C$ is also roasting of sulphide ore.

Which of the following reactions is an example of the calcination process?
