Iron Ore Mining Essentials: Key to Steel Production
The first step in the process is the production of pig iron from which the iron ore is converted in the blast furnace and usually occurs in the form of iron oxides. The heated air is blown into the furnace at the bottom which assist in the coking to be burnt and to produce high temperatures (about 1,500°C).
