Iron Ore Extraction Blast Furnace

Iron Extraction Blast Furnace Metallurgy

The extraction of iron from its ore is a complex process since it involves the use of a blast furnace. The introduction of the ore of iron and several other chemical compounds in the blast furnace result in the extraction of iron. The main raw material used for the extraction process is coke, which contains carbon.
