उत्तर
- The process of heating of sulphide ores strongly in excess of air to convert it into respective oxide is called roasting.
- For example, zinc sulphide is heated strongly in excess of air to convert it to zinc oxide.
\[\ce{\underset{\text{Zinc sulphide}}{2ZnS_{(s)}} + 3O_{2(g)} -> \underset{\text{Zinc oxide}}{2ZnO_{(s)}} + \underset{\text{Sulphur dioxide}}{2SO_2↑}}\]
