Iron ore agglomeration is a wet agglomeration process, and moist "greenballs" are subsequently dried and heat hardened at high temperatures to make pellets; the presence of binders affects the entire process from greenball formation to pellet hardening.

Finally, it offers a brief description of iron making processes and correlations related to the agglomerates: quality parameters and BF productivity and coke rate.
The physical and chemical properties such as particle size, montmorillonite content, swelling degree, water absorption, and blue absorption of A, B, and C bentonites were studied under laboratory conditions. The effects of adding different quality and different proportion of bentonite on falling strength, compression strength, and shock temperature of green pellet were investigated. The ...

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 lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

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 highgrade 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 agglomeration ...

Pellets around 410 mesh provide a happy medium between iron ore fines (crushed/ground iron ore) and a chunk of iron (mined) for use in a blast furnace. Pelletization offers an effective solution to the items noted above. The ''recipe'' for successful pelletization, however, is determined through testing. Iron Ore Agglomeration Tests

The green balls are spherical agglomerates nominally mm in diameter, formed by rolling a moist mixture of finely ground iron ore concentrate, binder and sometimes a flux. The principle bonding mechanism in the green balls is the surface tension of water which is augmented by the binder.
As there can be significant variation in process requirements and sources of iron ore fines, testing is often an essential part of the development of a successful iron ore pelletizing operation. Different sources of iron ore will respond differently to agglomeration, and process requirements will subsequently vary.
Agglomeration The iron ore Fines are obtained by screening of good grade ores or flue dust or pyrite residue from sulphur production unit and the like need to be agglomerated in to lumps of suitable physical characteristics for rendering them useful as a blast furnace feed.
