Introduction to Iron ore Pellets and Pelletizing processes
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).

Iron Ore Agglomeration Technologies
Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron …
Advances in Sintering and Pellet Technology
The objective of iron ore agglomeration is to generate a suitable product of granules in terms of thermal, mechanical, physical, and chemical properties. Sintering and pelletization processes are largely influenced by the source of iron ore and the way in which the beneficiation flowsheet is adopted.

Iron ore pelletization
Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world's high-grade competent iron ore resources. In addition, more iron ore concentrates are being ...
Examining low nitrogen oxides combustion in iron ore sintering
The iron ore sintering contributes to more than half of worldwide steel production's total NO x and SO 2 emissions. Globally, a considerable output of iron ore sinter is achieved through sintering processes. Sintering is a significant energy consumer in ironmaking, ranking as the second-largest energy-intensive process after blast furnaces.

New Paradigms for Iron Ore Pelletization | SpringerLink
Thus, in iron ore pelletization, class C and class F fly-ashes may both undergo pozzolanic reactions. Fly-ashes which do not meet ASTM C618 may still be useful as pellet binders, so long as they are pozzolanic. These fly-ashes are generally disposed of in landfill as solid waste, as they are unsuitable for use in construction materials or cement.
Iron Ore Pelletizing Process: An Overview
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. ... :010901/1-010901/5 [28] Wynnckyj J, Fahidy T.
