Iron ore is a compound of iron (Fe), oxygen (O) and other minerals. It is a natural mineral that is mined from earth. These mines are auctioned by the government and then handed over to the manufacturers for extraction and use. Iron ore is mined and then converted into iron in the blast furnace, where it is mixed with coal.
