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
