Roasting - In this process, an ore is converted into its oxide by heating it strongly in excess of air. This method is commonly used for sulphide ores. During roasting, moisture and non metallic impurities are also removed as volatile gases .
For example: Zinc sulphide is converted into zinc oxide by roasting.
