Nippon Steel Carbon Neutral Vision 2050

iron ore as carbon is more reactive than iron (Fe). In nature, iron exists as oxides, iron ore. To produce steel products, oxygen must be removed (= reduced) from iron ore. The use of carbon (coal) is the best, stable, cost-effective method for reducing iron ore in large quantities. The reaction, however, emits CO2. Reduction Melting Refining ...
