Solution

Aluminum can only be extracted by electrolytic reduction of its oxide, not by carbon reduction
Aluminium can't be extracted from its ore by reduction with carbon as it is more reactive to carbon, so the electrolytic reduction is done to obtain Al.
Aluminum is a metal that is comparatively higher in the electrochemical series, extracted by electrolysis.
The electrolyte used for the extraction is ${Al}_{2} O_{3}$ dissolved in molten cryolite.
