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 Separation Of Iron-.

About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes, fittings, engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile.

The production of iron from its ore involves a redox reaction carried out in a blast furnace. The furnace is filled at the top with the iron ore oxide most commonly hematite ((Fe_2O_3)) but can also magnetite ((Fe_3O_4)), carbon called coke and limestone ((CaCO_3)). For the purpose of this discussion the iron ore oxide hematite …

Iron ore accounted for 93% of the metals mined in 2021, with 2.6 billion tonnes extracted from the ground. It's important to note that this is ore production, which is typically higher than metal production since metals are extracted and refined from ores. For example, the iron metal content of this ore is estimated at 1.6 billion tonnes.
