Iron is made from iron ore, that is any rock such as Magnetite, Hematite, Limonite or Goethitite. Iron consists of iron and oxygen atoms that are bonded together. In order to get iron, the ore must be deoxygenated to leave only iron atoms behind. Heat is needed for this process and because coal is easily available, it is used to heat the ore to get the oxygen out and what is left is called wrought iron. In order to create steel, more heat need and the ore must be mixed with up to %1.5 carbon but no oxygen and any kind of impurity.
