The extraction of iron from its ore is a very long and forlorn process that separates the useful components from the waste materials such as slag What happens in the Blast Furnace? A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottomIron oxide, the ore from which iron to be extracted, is concentrated by roasting or calcination impurities can be eliminated Removal of Volatile Impurities by Roasting and Calcination H 2 O → H 2 O(g)↑ (Water Vapour) CaCO 3 → CaO(s) + CO 2 (g)↑ (Carbon dioxide) 2FeS + 3O 2 → 2FeO + 2SO 2 (g)↑ (Sulphur dioxide) This concentrated ore is mixed with limestone and coke, and sent into aNotes On Extraction Of Iron From Its Oxides CBSE Class
