Processes and Procedures in the Extraction of Iron
Feb 15, 2021 The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnaceThis concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top It is in the blast furnace that extraction of iron occurs The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such Extraction of Iron Metallurgy Blast Furnace and ReactionsIron is extracted from iron ore in a huge container called a blast furnace Iron ores such as haematite contain iron (III) oxide, Fe2O3 The oxygen must be removed from the iron (III) oxide inExtracting iron Redox, extraction of iron and transition
