extraction of iron and production of steel

Iron extraction and steelmaking - Chem Not Cheem

2020-8-18  8. Beyond the 3Rs: reworking the extraction of iron. Be that as it may, many countries depend on cheap steel to industrialise and uplift the poor. We cannot simply force them to reduce their steel consumption or use recycled steel that is more expensive. One way to have the cake and eat it is to change the way we reduce haematite to iron.
