Iron Ore: From Mining to Processing to Dust Control

Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.

How is Iron Extracted from Iron Ore | Actforlibraries

C + O2 → CO2. The heat produced by this reaction is the main source of heat in the blast furnace that is used for iron production. At the bottom of the furnace, the temperature is very high, which causes more of the coke to react with carbon dioxide, producing carbon monoxide. C + CO2 → 2CO. The carbon monoxide then becomes the "reducing ...

Extraction of Iron: Meaning, Purification, & Extraction Methods

The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.
