Iron and SteelMaking Process | SpringerLink

Iron is extracted in the form of metallic iron (Fe) by reducing the oxide ores with a reducing agent. The principal agents commonly employed to serve this reduction process are the naturally occurring forms of carbon such as coke, charcoal and coal. In order to extract the iron, Fe (5560%)rich ore is usually used.

Making iron steel blast furnace | ArcelorMittal

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two ...
