Zinc blende ore can be converted into zinc oxide by the process of (a) Roasting (b) Hydrogenation (c) Chlorination (d) Calcination

Solution:

Option (a) is the answer. Zinc blende (also known as zinc sulphide or ZnS) is a zinc sulphide ore. Roasting (heating in the presence of air) converts sulphide ores to metal oxides. Zinc blende is transformed to zinc oxide when heated in the presence of excess air.
