Blast Furnace Ironmaking
D. Zhu, in Iron Ore, 2015. Abstract. The blast furnace (BF) ironmaking process is currently the dominant process for providing steelmaking raw materials worldwide. However, the BF process relies heavily on metallurgical coke and involves cokemaking and sintering operations, which often attract serious environmental concerns.

How Iron Is Made
To convert iron ore into metallic iron, oxygen and impurities must be removed.This process requires heat and a reducing agent, a substance that combines with the oxygen and releases it from the ore.. In the blast furnace process, iron ore, coke (processed coal), and limestone (the charge) are poured into a vessel lined with refractory (heat-resistant brick).
