When iron ore fines undergo the process of pelletization they produce iron ore pellets which are of uniformly size. During pelletization, the iron ore fines are mixed with certain additives such as bentonite and are then converted into oval lumps using a pelletizer. The balls undergo the hardening process by firing them with fuel.

in iron ore pelletization With the depletion of higher grade ore deposits, the extraction of lower grade ores gained in importance. The ores are ground to a fine particle size to separate unwanted impurities and con-centrate the iron oxide. The fine grain of the concentrate is then agglomerated into larger particles to allow further processing in

Iron ore fines The IMSBC Code definition for iron ore refers to cargo in the size range of up to 250mm, and iron ore fines 10% or more of fine particles of less than 1mm and 50% or more of particles less than 10mm. Moisture contents quoted for iron ore fines typically vary between 6 12%, with iron to ore having lower moisture content.

Abstract: Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets.

The process of pelletization enables converting Iron Ore Fines into "Uniformed Sized Iron Ore Pellets" 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.

The most important iron ore pelletization parameters that affect the agglomeration are wetting-nucleation, consolidation - growth and attrition-breakage [26, 27]. This paper outlines the upgrading process as well as pelletization of iron ore fines and the …

Iron ore fines with comparatively high Al2O3 content exhibit different pelletizing characteristics. As for the firing of hematite iron ores, more heat is required to be supplied from external sources due to the absence of the following exothermic reaction of oxidation of magnetite.

Iron ore fines (pellet feed) are pelletized for utilization in DRI & BF processes. In the present pelletization technology i.e., straight grate and grate kiln processes, the LOI in the ore should be within the range of 2.0-2.5%. LOI content in the iron ore concentrate is found to be more than 4% after beneficiation of low-grade iron ore.

In Orissa, approximately, 5.5 million tons of iron ore fines are produced per year. Availability of such a huge quantity of iron ore fines in India and Orissa justify the establishment of pelletization units based on regular supply of raw material to sustain the unit’s functionality.

IOP (Iron Ore Pelletization) includes the bentonites used in the production of iron ore pellets for foundry processes (blast furnaces). They are sodium bentonites with elevated colloidal and binding properties, which mixed with iron ore fines and subjected to a mechanical agglomeration process, form compact pellets with high mechanical performance.
