Iron Ore Pelletization is an agglomeration process of the disintegrated Iron Ore fines into Iron ore Pellet which is suitable for the utilization of downstream process of Iron Making.
Mar 19, 2008· Iron ore, its beneficiation and agglomeration as required for iron and steel industry: A. Iron Ore: A naturally occurring mineral from which iron (Fe) metal is extracted in various forms viz Hot metal/ DRI etc.. B. Types of Ore: Two major varieties used for iron making are Haematite Ore ( containing Ferric Oxide Fe2O3) and Magnetite Ore (containing FerroFerric Oxide – Fe3O4).

Organic (no more used in iron ore pelletization) Inorganic Inorganic binders are bentonite, Ca(OH) 2, Lime etc. Bentonite is more commonly used in pelletization of iron ore. It contains 6070% SiO2 and 1520% Al 2O3. It combines with water and form a gel 5 to 6 times of .
Pelletization is one such process which uses water as medium and revolving units (Disc/Drums) to form spherical pellets from fine particulates. Green or wet pelletization is the first step in pelletization process and is of critical importance since the effectiveness of the subsequent stages of drying and in duration depends on the quality and quantity of green pellets.

The Table 4 shows the size distribution of iron ore and coke used. Pelletization Schematic of the experimental is presented in . A Fig. 1 part of dry Noamundi iron ore fines was ground for 18 minutes to –45 μm (56% approx). The size distribution and Blaine fineness of it is shown in Table 5. The iron ore .
The formation of raw iron ore pellets, also known as pelletizing, has the objective of producing pellets in an appropriate band of sizes and with mechanical properties high usefulness during the stresses of transference, transport, and use. Both mechanical force and thermal processes are used to produce the correct pellet properties.
Clay minerals are among the most frequently used binders in iron ore pelletization. The main advantage of clay minerals is their good wettability, their great adhesive and cohesive force, which provides sufficient mechanical stability of the finished pellets, as well as their thermal stability. ... Binder composition for the agglomeration of ...
What is Pelletization? The process of Pelletization helps converting Iron Ore Fines into "Uniform Size Iron Ore Pellets" that can be fed in the blast furnaces or in the DRI kiln (DRI). Why Pelletization? Pelletization is the only answer to a major question of preserving our precious iron ore and using it .
iron ore pelletization Pelletizing is the process through which ground iron ore fines are transformed into heat hardened spheres called "iron ore pellets". These pellets are suitable for use in an ironmaking furnace such as a blast furnace or electric arc furnace.
Chemistry and Physics of Taconite Agglomeration . PDF (Minnesota Department of Natural Resources, 3/2/19996/30/2007) While pelletization of iron ore concentrate has been used for many years, the process was for the most part developed empirically, and so the chemistry and physics of the actual pelletization process had not been studied.
WHAT IS PELLETIZATION ? 12 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 .
Iron mineral pelletizing results in better performance in blast furnaces by facilitating the circulation of air and gases between the different components of the blast furnace charge. Historically, the raw material for blast furnaces was fragments of iron ore from highgrade deposits.

Organic binders generally do not contain high quantities of silica and alumina and are burnt during preheating, contrary to bentonite clays commonly used in pelletizing iron ore for blast furnaces. Due to the need to process increasing volumes of low grade iron, interest in organic binders has increased lately.
After beneficiation iron ore availability can improve by about 50%. Steel community and the country demand technological solutions for utilising low grade ores. The technology task that would be imperative: 1. Utilisation of low grade iron ores after beneficiation. 2. Reduction in slime loss by recovery of iron values from slimes. 3.
