Aluminium has high affinity for oxygen so cannot be reduced by carbon

Metals such as zinc, iron, and copper are present in ores as their oxides. Each of these oxides is heated with carbon to obtain the metal. The metal oxide loses oxygen and is therefore reduced.
However, there are few metals, like aluminum which are so reactive that their oxides cannot be reduced by carbon. These metals have more affinity for oxygen than carbon. so carbon is unable to remove oxygen from these metal oxides and hence they cannot be converted into free metals.
