Input iron ore: Input iron ore is in form of cooked pellet in this process and high grade hematite iron ore can be used to a certain extent depending on its condition. Reducing agent: Natural gas is broken after the reforming process. In the Midrex process, carbon monoxide gas has a larger share than hydrogen gas in the reducing gas mixture.
