Oxide ores are subjected to roasting to remove the volatile impurities in the form of their oxides. It is easier to obtain metals from their oxides (by reduction) than from carbonates or sulphides. So before reduction can be done, the ore is converted into metal oxide.

Explanation:

Importance of Roasting Oxide Ores:
Roasting is a process used to convert sulfide ores to oxides before further processing. Oxide ores are then subjected to roasting for several reasons, with one of the main reasons being:

Removal of Volatile Impurities:
- Roasting helps in the removal of volatile impurities present in the ore in the form of their oxides.
- When the ore is heated, volatile impurities such as arsenic, sulfur, and carbon are converted into their respective oxides and driven off.
- This process ensures that the impurities are removed from the ore before further processing, leading to a purer final product.
In conclusion, the primary purpose of subjecting oxide ores to roasting is to eliminate volatile impurities in the form of oxides, ensuring a cleaner and more refined end product.
