Extracting metals using electrolysis

Reduction method of extracting metals using carbon is much cheaper. Carbon is cheap and also acts as a fuel to provide energy (heat) needed for metal extraction. Hence, metals lower in the reactivity series are cheaper to extract in large industrial set ups, than those higher up in the reactivity series.
