For example, it is an iron atom in haemoglobin that is responsible for carrying oxygen around the blood stream. Iron is not found as the free metal in nature. The most common ore is haematite (iron oxide, Fe203). Iron is found in other minerals such as magnetite, which is seen as black sands along beaches. The core of the earth, more than 2000 in radius, is composed largely of iron.
