It may not have the immediate glamour of a precious metal, like gold, but is nevertheless vital for economic growth.
Steel itself is used in a myriad of everyday products - from household items such as fridges and washing machines, to cars, buses, trains and the steel girders used in most office buildings.
Three big mining companies, Rio Tinto, Vale and BHP Billiton, dominate the global market in iron ore.
