remaining is exported. the bulk (around90%) of the iron ore fines get exported, as they cannot by utilised in iron making without agglomeration [3]. As the demand of iron ore is increasing, it is necessary to recover the resources from the mines wastes or leangrade iron ore through beneficiation. In that case the feed to sinter or pellet can be

Abstract Factors affecting the bonding efficiency of bentonite during pelletising were investigated. Results show that it is influenced by the properties of bentonite, water and iron ore concentrate. The dosage of bentonite can be halved by exchanging cations in the interlayer to activate bentonite, removing bivalent cations to soften the water and milling the mixture to advance the contact ...

For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

1. Iron ore supply and demand outline Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
