  • Extraction of Iron from its ores, Iron dressing,

    Iron ( 26 Fe: (18 Ar), 4S 2, 3d 6 ) is found in the earth’s crust in the form of natural ores which contains different iron oxides mixed with impurities such as Silica (SiO 2), (Al 2 O 3), CaO, and MgO, and some harmful impurities such as s, p and As, The suitability of the ore in the extraction of iron economically depends on three factors which are:Blast furnace ironmaking is inseparable from the coke source, but the coke resources are getting less and less, but the price is getting higher and higher, the cost of iron making will be higher and higher, and it is likely that one day will meet the depletion of coke resources 2 The blast furnace ironmaking damages the environment very much 3What are the Advantages and Disadvantages of BlastThe following questions are about the blast furnace and the production of iron a) Why are hot blasts of air blown in to the blast furnace?
