Iron Ore Processing: From Extraction to Manufacturing
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
Lesson Explainer: Extracting Iron | Nagwa
Blast furnaces are a common part of large industrial steelmaking plants, which also include coke ovens, sintering beds, and other areas for ore dressing. Iron is extracted from its ore using carbon in the form of coke. An iron-containing ore is combined with coke and limestone to form what is known as the charge.
