Extraction of Iron | Metallurgy | Blast Furnace and Reactions
WEBExtraction of Iron. Extraction of iron from its ore is the third and the penultimate process in the Metallurgy. The extraction of metals and its isolation occurs over a few major steps: Concentration of Ore; Extraction of metal from concentrated Ore; Purification of the metal; How is iron extracted from its ore?
Iron ore - Wikipedia
WEBIron ores[1] are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe. 3O. 4, 72.4% Fe), hematite (Fe. 2O.
