Give the reaction involved during the extraction of zinc from its ore by
(a) roasting of zinc ore
(b) calcination of zinc ore

(a) Roasting of zinc ore
Roasting is a process of metallurgy where ore is converted into its oxide by heating it below its melting point in the presence of excess air.
$2ZnS + 3O_2→2ZnO + 2SO_2$

(b) Calcination of zinc ore
Calcination is defined as the process of converting ore into an oxide by heating it strongly in the absence of air.
