The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 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).
