2 Steel Industry: Production Processes

Therefore, there is a continuing demand for primary steel. In essence, all primary iron and steel production processes are based on the same chemical reactions. 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.
