Electrolysis is a very expensive process because of the cost of electrical energy. Carbon Zinc Iron Lead Zn Fe Pb Reduction of the metal oxides in a blast furnace. Carbon is used as the reducing agent. It is often in the form of coke (made from coal). Although this uses a lot of energy‚ this is cheaper than using electricity.
