Iron is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space.

The decline in iron ore prices, in recent times, has raised questions about the sustainability of iron ore mining projects worldwide. Expanded production, by the big three mining companies, has created stiff competition in a market that has been experiencing a slowdown in demand. Some iron ore mines, such as those in Canada, China and Africa, have buckled under the pressure. Nevertheless, producers with operating costs that are far below current iron ore prices are well-positioned to take market share.
