Blast Furnace - ScienceAid

Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500's.

Extraction of Iron Ore from a Blast Furnace. A metal such as iron, which is less reactive than carbon, can be extracted from its ore using carbon. Reactions in the blast furnace: C + O 2 > CO 2; The coke burns, to form carbon dioxide and to produce heat; CO 2 + C > 2CO; The carbon dioxide reacts with more hot coke to produce carbon monoxide gas.

In the blast furnace, it is so hot that carbon monoxide can be used to reduce the iron oxide in place of carbon: iron oxide + carbon monoxide → iron + carbon dioxide Fe 2 O 3 + 3CO → 2Fe + 3CO 2 Iron from the blast furnace is an alloy of about 96 per cent iron with carbon and some other impurities. It is hard, but too brittle for most uses.
