What chemical process is used for obtaining a metal from its oxide?
Metals from its oxide obtained from reduction. Metal oxide is reduced by this process, metal oxides are reduced by using suitable reducing agents such as carbon or by highly reactive metals to displace the metals from their oxides.
Example, On treating zinc oxide with carbon it reduces to metallic zinc.
Manganese dioxide is reduced to manganese when treated with aluminium powder, so aluminium displaces manganese from its oxide.
Oxides of more reactive metals are reduced by electrolysis.
