[Solved] The iron produced in the blast furnace

Content: Pig Iron: Pig iron is the product of smelting iron ore. Iron oxide must be reduced in order to obtain iron and this can be done only in a blast furnace.; Pig iron has a very high carbon content, typically 3.5 - 4.5%.; Wrought iron: Wrought iron is the purest form of iron. It is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%).
