Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world''s iron and steel industries.
Estimates of the tonnage and average grade of ore deposits (orereserve estimates) are made for various purposes. They may be made by examining engineers as a basis for placing a value on a mining property in connection with reports on behalf of owners or vendors, on the one hand, or for prospective purchasers or lessees, on the other.

Mineral veins exposed at the surface will be weathered, during which ore minerals are broken up by mechanical weathering or left as insoluble material by chemical weathering separating the ore and gangue minerals. The material is then transported, concentrated and sorted according to grain size, hardness and density by the action of flowing water.
