(D) Roasting is the process of heating an ore in a regular supply of air in a furnace at a temperature below the melting point of the metal. $ZnS$ (zinc blende) is a sulfide ore,and sulfide ores are always subjected to roasting,not calcination,to convert them into their respective oxides. Therefore,the statement that zinc blende is subjected to calcination is false.
