Mining methods can be divided into two general excavation types: open pit mining (surface mining methods) and underground mining (sub-surface). Mining types are also dependent on the valuable mineral resources being mined. For example, coal mining differs from the method used for valuable metals found in metal ores (e.g., iron ore).

Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth's crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:

Extraction and uses of Iron Reduction is used to extract iron from its ore (haematite) which is mainly iron(III) oxide. The iron ions are reduced to iron atoms, using carbon. This is oxidised to form carbon dioxide. iron(III) oxide + carbon iron + carbon dioxide 2 Fe2O3(s) + 3C(s) 4 Fe(l) + 3 CO2(g)
