Carbon reduction process is used to reduce less electropositive metals.

M g

and

A l

have high electropositivity.

M g O + C a t hi g h t e m p 200 0^{0} C M g + CO

It is possible at high temperatures, so it is not used for commercial purposes.

Hence, cannot be extracted from oxides through the carbon reduction process.
