If lump production is 30% of the pellet production, for example, the total iron ore flow from lump ore (Ml1 + Ml2) is only 0.12 t, which avoids 0.18 t of mined rock, compared to a base case requirement of 6.8 t for the production of pellets with 1 t of iron.
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.

Iron Ore is a basic type of ore which is abundant in the world. It is smelted into Iron Ingots or alloyed into Steel Ingots for further processing. Its Resource Scanner is unlocked after the pioneer leaves the drop-pod. Iron Ore can be harvested by hand (default E) in trace amounts from resource deposits scattered across the world, or from inexhaustible …
1. The Bessemer Process. The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which shaped like a huge concrete mixer (Fig. 4.2).The converter is made of steel plates lined inside with a refractory material. The type of refractory lining used depends upon the character of …

Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron …
Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
