    Sep 27, 2021 The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke

    Oct 23, 2018 The ore dressing. The aim of ore dressing is increasing the concentration of iron in the ore by removing the unwanted impurities and improve the properties of the ore which helps in the successive stages of extraction, The ore dressing process is carried out to improve the physical and mechanical properties of iron ore and includes Crushing process, Sintering process, Purification and

    Importance - Removal of iron impurities. - The iron (II) so formed during roasting is converted to iron (II) silicate, FeSiO 3. - The iron (II) silicate constitutes the major portion/component of the slag. Equation: FeO (s) + SiO 2(g) FeSiO 3(s) - The slag separates itself from the copper (I) sulphide

    Impurities in Pig Iron and their Effects: 1. Phosphorus: The quantity of phosphorus present in pig iron varies from 0.1 to 2.0%. It combines with iron to form Fe 3 P which embrittles cast iron. Phosphorus is introduced into iron from phosphate in the ore. Phosphates get reduced in the reducing atmosphere in the blast furnace and phosphorus is
