Sintering : In sintering fine mineral particles are agglomerated into a porous mass by incipient fusion caused by the heat produced by combustion within the mass itself. In this case the iron ore fines and other iron bearing recycling materials are mixed with fluxing material, moisture and solid fuel normally coke breeze and fed to the permeable grate of sintering machine.

The high hematite concentration is a characteristic of a processed ore, which was upgraded to use in a pelletizing plant. The sample moisture was at 6.57%, lower than 8–10% used in traditional pelletizing of iron ores. Table 4 shows the iron ore, bentonite and slaked lime compositions.

Agitative Agglomeration

Iron ore processing is the largest tonnage of material being pelletized by agitative agglomeration in which there is no chemical reaction between the particles and the liquid. Since it is a large tonnage product and since it is easy to study, much investigation has been done regarding this type of the ball formation.
