Difference Between Roasting and Calcination – Difference Wiki
Jun 15, 2019· Metal is obtained from its ore by the process of electrolysis or reduction. In the process of reduction, the ore that is reduced is an oxide ore. Oxide ore is much easier to reduce as compared to its carbonates and sulphides. If the ore is not an oxide ore then first it is converted to an oxide ore by the process of calcination or roasting.
