Question

to obtain metal from their metal oxide,which chemical process is used?give the chemical equations as well

Answer 1

The chemical process used for obtaining a metal from its oxide is reduction. ...
Manganese dioxide is reduced to manganese by treating it with aluminium powder. ...
Oxides of more reactive metals are reduced by electrolysis.

Answer 2

Heya mate
The answer of ur question is here

♢♢ This method is basically reduction of metal oxide to metal.The process used for reduction depends on the reactivity of the ore :-
1) For elements at the top of the activity series ⇒ Electrolysis
2) For elements in the middle of the reactivity series ⇒ Reduction by reducing agent like  Carbon , Carbon Monoxide , Hydrogen
3) For elements at the bottom of the reactivity series ⇒ Heating only

hope it helps you
