  • The Step-by-Step Process of Producing Iron from Iron Ore

     · The Step-by-Step Process of Producing Iron from Iron Ore. Some years ago the ancient Egyptians derived iron from the fallen meteorites (or so they say) carved them and made tools and equipment besides jewelry. We have come a long way since then. Now first of all pure iron is rarely available (except if one or two meteorites crash).
