Quizplus · Accepted Answer

Smelting of iron ore involves heating beyond ironʹs melting point and combining the material with carbon. This process is known as the blast furnace process, and it is used to extract iron from its ore. The carbon reacts with the oxygen in the iron ore to produce carbon dioxide and carbon monoxide, which then reducethe iron oxide to iron metal.
