Geographically, the flow of iron ore is the physical movement among the areas of production and consumption. By visualizing the flow of iron ore as the motion of particle, and considering the motive of flow as the function of some force, the field theory can be applied to reveal the generation reasons and operation mechanism of iron ore flow.

The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural iron-bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore.

This is even harder than pig iron. Wrought Iron/ Malleable Iron. Wrought iron is the purest form of iron available commercially available and is prepared from cast iron by heating cast iron in a furnace lined with Haematite (Fe 2 O 3). The Haematite reacts with Carbon in the cast iron to give pure iron and carbon monoxide gas which escapes.

They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole.
