What determines whether an element can be reduced with carbon
The position of the metal in the reactivity series determines whether it can be extracted by reduction with carbon.

Which elements can be reduced with carbon?
Metals below carbon in the reactivity series can be extracted by reduction using carbon. For example, iron oxide is reduced in the blast furnace to make iron. This is because carbon can only take the oxygen away from metals which are less reactive.

Which elements cannot be reduced by carbon?
Metals higher in the reactivity series have to be extracted using electrolysis, which is expensive.
