Giving examples to differentiate roasting and calcination

Roasting: The process of heating the mineral to high temperature in presence of air (or) oxygen is called roasting. During roasting volatile impurities are removed in the form of oxides.
Ex: $2\mathrm{ZnS}+3{\mathrm{O}}_2\to 2\mathrm{ZnO}+2{\mathrm{SO}}_2$
$\mathrm{ZnS}+2{\mathrm{O}}_2\to {\mathrm{ZnSO}}_4$
Calcination:- The process of heating the mineral to high temperature in the absence of air is called calcination.
During calcination volatile impurities are removed.
$\mathbf{Ex}\mathbf{:}\text{ 1) }{\mathrm{CaCO}}_3\stackrel{\mathrm{\Delta }}{\to }\mathrm{CaO}+{\mathrm{CO}}_2$
$2{\mathrm{NaHCO}}_3\stackrel{\mathrm{\Delta }}{\to }{\mathrm{Na}}_2{\mathrm{CO}}_3+{\mathrm{H}}_2\mathrm{O}+{\mathrm{CO}}_2$
