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

2017-10-23  The raw materials mix or “charge” enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now, this carbon monoxide that is unstable, reacts with the ore to form carbon dioxide and iron.

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

2017-10-23  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).
