Sponge iron being magnetic gets attracted and gets separated from non- magnetic char. The iron ore and coal crushed and screened to respective sizes are fed to rotary kiln through feed tube in pre-determined ratio. The rotary kiln is slightly inclined at an angle 2.5 deg and rotated by
to BHP Billiton iron ores (e.g., MACTM Fines Fe 61.8%, SiO 2 3.0%, Al 2 O 3 1.9, CaO 0.03%, MgO 0.06%), the concentrates are high in CaO and MgO and low in Al 2 O 3 /SiO 2 ratio. Tab le 2gives the mineralogy for the above magnetite concentrates. Magnetite is the main iron oxide and hematite is also present. Ores E1 and E2 contain siderite. The
Oct 01, 2020 Extractive Metallurgy Sponge Iron Making. Oct 11, 2013 When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. Hence the name sponge iron. The Main Raw Material are Primary ore Secondary Iron Ore (Magnetite or Hematite), Iron sand also can be used but it should be a Pellet first.
