01/12/2020 · In extracting metals, carbon in the form of coke is used. Carbon is widely used in the extraction of zinc, iron, tin and lead for a number of reasons: (a) First of all, carbon is more reactive than zinc, iron, tin and lead. Therefore, carbon can easily reduce the oxide of these metals. (b) Furthermore, carbon is cheap and easily available.
