Ironmaking 101 – From Ore to Iron with Blast Furnaces ...

Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore.
