2 Steel Industry: Production Processes

In iron ore, iron is presents in its oxidised form. In iron reduction processes, a reducing agent, based on carbon or hydrogen, removes the oxygen from the iron. This removal can take place either above or below the melting point of the ore and the reduced iron. Reduction above the melting point results in pig iron. Above the melting point, most of the gangue materials …
