Iron is the first element in the eighth column of the periodic table. It is classified as a transition metal. Iron atoms have 26 electrons and 26 protons with 30 neutrons occuring in the most abundant isotope. It is the sixth most abundant element in the universe. Characteristics and Properties In its pure form iron is a fairly soft, grayish metal.

Physical Properties of Iron Element. Pure iron is known to be a soft metal, with a silver white or grayish color. Some of its most important properties are ductility, malleability and thermal conductivity. Malleability lets Iron be beaten into sheets, without cleavage and ductility makes it possible for thin wires to be drawn from it.

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).

This processing works to transform raw, mined iron ore into a concentrated powder suitable for pelletizing. In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it can be utilized, as opposed to disposed of. The Pelletizing Process

Cast iron, an alloy of iron (Fe) and carbon (C), has gained popularity in the market because of its low cost. It has the ability to build composite structures. The amount of carbon in cast iron is 2 – % of its weight. Besides iron and carbon, this alloy contains silicon (Si), small amounts of manganese (Mn), sulfur (S), and phosphorus (P).

The smaller sized iron ore fines (<100 mesh) shall reduce the permeability of sinter bed and this in turn will generate more sinter returnfines and thus productivity of sinter machine is affected. So the ideal size distribution of iron ore fines must be 10 to mm and mean size of the ore fines shall be 3 to 5 mm.
