Iron ore - Wikipedia

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

Molten Steel in the Debris Pile, Cool Down Time? | Metabunk

A large fraction of the thermite will turn to aluminum oxide and be lost, but we will ignore this and assume an initial 10-ton sphere of molten iron at 2,500 C. The density of molten iron is around 7,000 kg/m^3, so 10,000 kg of iron occupies about 1.3 m^3, in the form of a sphere with a diameter of about 1.2 m.

How is Iron Made Into Steel? | Sciencing

Iron was the dominant metal for use in building and machinery until the modern era. Iron is still the main component of steel but when impurities are removed in the steel-making process, a stronger, lighter material results (steel). Steel is used in almost all modern buildings, automobiles, aircraft and appliances.
