Iron Extraction by Blast Furnace Metallurgy
Iron extraction by blast furnace metallurgy is an extremely important concept which shows what happens after the iron has been extracted from iron ore in a blast furnace. This whole process is a reduction reaction where oxygen is removed from the iron (III) oxide to leave behind iron. This process of metallurgy is taught in-depth in chapter 6 ...

Extraction of iron on a match head
Iron(III) oxide + carbon → iron + carbon dioxide. 2Fe 2 O 3 (s) + 3C(s) → 4Fe(s) + 3CO 2 (g) Carbon is more reactive than iron. The iron oxide is reduced by the carbon (the oxygen is removed) to form metallic iron. The sodium carbonate fuses easily and brings the iron oxide into close contact with the carbon.
