  • Blast Furnaces Extract Pure Iron From The Iron (iii) Oxide

    Blast Furnaces Extract Pure Iron From The Iron (iii) Oxide

    This is why we do not find pure iron in the Earth’s crust. Instead it is found as an ore, in which iron is chemically combined with oxygen or other non-metals. Most workable iron ores are rich in iron (III) oxide, Fe2O3. Making iron by removing oxygen from the ore is the first step in the manufacture of steel. Reduction and oxidation.The steel industry represents about 7 of the world’s anthropogenic CO2 emissions due to the high use of fossil fuels. The CO2-lean direct reduction of iron ore with hydrogen is considered to offer a high potential to reduce CO2 emissions, and this direct reduction of Fe2O3 powder is investigated in this research. The H2 reduction reaction kinetics and fluidization characteristics of fine.
