  22.5: Reduction of Metals - Chemistry LibreTexts

  Since iron is the most important metal in our industrial civilization, its reduction from iron ore in a blast furnace (Figure 22.5.1 22.5. 1 ) deserves a detailed description. The oxides present in most iron ores are Fe 2 O 3 and Fe 3 O 4. These oxides are reduced stepwise: first to FeO and then to Fe.

  Iron Ore | HowStuffWorks

  Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores. The most primitive facility used to smelt iron is a bloomery. There, a blacksmith burns charcoal with iron ore and ...
