2021-11-9 · Raw iron producers are major greenhouse-gas pollutants. The CO 2 footprint of a pig-iron plant is mainly governed by the overall oxidation state (Fe 2+ /Fe 3+) of iron in the ore. The oxidation state determines the amount of reducing agent (coal) in raw iron production and is obtained from the mineralogy of the ore.
