Carbon can't be used as reducing agent for MgO because Magnesium is high in the reactivity series and metals high in the reactivity series have more affinity for oxygen than carbon.

It is done by an electrolytic process.

Cu is obtained in two steps:

1) first heating the sulphide ore in the presence of oxygen to get copper oxide.

2) then heating the oxide with the sulphide as reducing agent to get Copper.
