WebMetals below carbon can be extracted in a reduction reaction with carbon. Carbon will out compete a metal below it in the reactivity series for an ore’s oxygen. This is called a reduction reaction as it reduces the metal oxide to a metal element.

Why are highly reactive metals extracted by electrolysis?

WebMetals above carbon in the reactivity series cannot be extracted from their oxides by heating with carbon. This is because the metal bonds to oxygen too strongly and the carbon is not reactive enough to remove it. So we have to use electrolysis to extract metals more reactive than carbon, such as aluminium, magnesium and calcium.
