Iron and Steel industry is considered the backbone of industrial development. The mining of iron ore has a prime importance among all the minerals mined in our country.1,2 In recent years, Government of India (GoI) has stipulated a rule to use iron ore up to 45% Fe not to dump fines and slimes as waste, so to conserve the limited reserves

PELLETISATION - Metal Bulletin

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. This process is physically developed to utilize the blue dust generated during the mining of hematite ore which could not be directly used in

01/01/2015 Technology The process of pelletization enables converting Iron Ore Fines into â€œUniformed Sized Iron Ore Pelletsâ€� that can be charged into the blast furnaces or for Production of Direct Reduced Iron (DRI). Pellets are uniform size, with purity of 63%- 65% contributing to faster reduction and high metallization rates.

Pelletisation of iron ore fines involves formation of spherical – shaped agglomerates by binding their concentrates using moisture and, if required, binding agents, followed by firing at high temperatures to establish permanent

Introduction to Iron ore Pellets and Pelletizing processes ...

23/02/2013 Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel. It is an agglomerating process of converting iron ore fines into ‘uniformed sized iron ore pellets’

Iron ore pelletization - ScienceDirect

01/01/2015 Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes. The pelletization process is very widely used, particularly when

Iron Ore Pelletization Technology and its Environmental ...

01/01/2015 Iron Ore Fines/blue dust cannot be charged in the blast furnace directly since they block the passage for ascending gas inside the feed. Moreover, the excessive fines generated from the iron ore crushing units are mostly stored as waste. If we look at it, we find that the growth rate of steel industry has slowed down from 12.7% in 2009-10 to 4.4% in 2011-12. Amongst the various reasons for ...

Iron ore pelletisation units must seek green clearance:

28/05/2014 Pelletising is part of steel making that involves conversion of iron ore fines into pellets. The use of pellets in the blast furnace helps in better flow of reactant gases inside it, and increases its overall efficiency and productivity. The iron ore pelletisation plant of Ardent Steel Limited in Keonjhar has a capacity to produce 0.6 million tones of pellets per annum (MTPA). It had obtained ...

Pellet Plant Process - Baldota

Raw material iron ore fines are fed to Iron ore grinding system (IOGS – 160 t/h) for grinding the ore to 85% -200 mesh. We use the wet grinding process for this. The slurry produced is then fed to filter press. For pelletisation, we require filter cake of 8.5% to 9% moisture, therefore we are adopting Pressure Filter supplied by M/s Outotec ...

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). Ores ...
