Pelletisation is a process of agglomeration of super fine iron ore into a heat hardened spherical ball of sizes 9 to 16 mm with the help of additives like bentonite, hydrated lime, coke fines, dolomite, etc.
blast furnace slag for pelletisation of iron ore. In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
Blast furnace is a reactor to produce iron. Ore reaches molten state and gets separated physically due to density from gangue and impurities. Presence of excess carbon reduces the melting point of iron to 1150oC. Integrated Steel Plants refer to Liquid Iron as Hot metal Pig Iron allusion to suckling Pigs in Sand molds of a cast floor.
Pelletisation of iron ores is also of great importance even with the vast highgrade iron ore deposits. In such areas, this unit operation is producing suitable blast furnace or DR feed from the rising mountains of high grade iron ore fines that are unavoidably created during crushing of .
Dec 10, 2019 Ground granulated blast furnace slag (GGBFS) is the byproduct in the production of metallic iron, whose main chemical compositions are CaO, SiO 2, Al 2 O 3, etc.,,,. The modern blast furnaces produce 250–350 kg slag per ton of pig iron, depending upon the iron content of the ore .

1500 °C. Molten iron and slag are drawn off at regular intervals from tap holes at the base of the furnace. The quenching of this liquid slag with an excess of water (granulation), air and water (pelletisation) or steam forms a granular product. For each ton iron about tons raw material, 330 kg coke, 150 kg coke coal powder and
Bentonite is the most common binder used in iron ore pelletisation owing to its good bonding properties in green and dry pellets at both ambient and elevated temperatures. However, due to its high alumina and silica content, it increases the slag volume and energy consumption in downstream processes. Organic binders may be used to replace bentonite; however, they fail to provide strength at a ...
