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.

Hematite, also spelled as haematite, is a common iron oxide with the formula Fe 2 O 3 and is widespread in rocks and soils Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundumHematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).

The ore grade, or concentration of an ore mineral or metal, as well as its form of occurrence, will directly affect the costs associated with mining the ore The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore.
