Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; …

The product of iron processing is iron concentrate or granulated iron ore. In general, there are 5 stages in processing of iron including crushing, grinding, magnetic separation, flotation and thickening (filtering). Crushing The ore crushing is usually done in 2 ore 3 steps to obtain a considerable particle size for grinding circuits.

Softening and melting of the ore takes place here, droplets of metal and slag forming and trickling down through a layer of coke to collect on the hearth. The conditions that cause the chemical reduction of iron oxides to occur also affect other oxides.
