Ninety-eight percent of iron ore mined goes into producing steel, the world's most common metal. By definition, steel is the element iron (99%) combined with carbon (1%). The iron in iron ore comes from iron oxides found in deposits such as massive hematite (the most commonly mined), magnetite, titanomagnetite, and pisolitic ironstone.

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …

Steel is the backbone of modern civilisations; without it, we'd be literally back in the dark ages. Used in almost anything you can imagine, iron and its purer form, steel, are crucial in everything from tin cans to appliances to the most monumental human constructions like bridges and city towers.
