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".

University of Minnesota's Mineral Pages: Hematite

Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist.

Smelting is a five step process. First, iron ore is crushed and mixed with crushed limestone and coke, which is carbon rich. Second, the mixture is placed in a blast furnace, where extremely hot air is blown through, making the coke burn.

How Is Iron Extracted From the Earth? | Reference.com

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

How is Iron Refined From the Ore? - innovateus.net

Iron ore refining process uses heat and another substance, so that oxygen molecule can bond to them and separate from iron. Carbon readily bonds with oxygen and so coal or coke (a form or carbon ) is used in the iron ore refining process.
