1. Preprocessing Before pelletizing, iron ore has to go through a pretreatment stage. Generally, the lowgrade iron ore raw ore needs a beneficiation process to upgrade into iron fines that suit pelletization. The beneficiation process varies depending on the iron ore types and mineral properties.
Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the interparticle bonding within the pellet.
The dominant process adopted to produce iron ore pellets in China is the gratekiln process [1012]. The preheated pellets roll in the rotary kiln and can be sintered uniformly; therefore, it is known that the gratekiln method yields a superior and more consistent pellet quality compared with the straightgrate process [13].

The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning

The concentrate slurry is fed to the filtration process where it is dewatered by pressure filters. ... The main raw material for the pellet plant is iron ore, which comes as slurry from the beneficiation plant through the pipe line ...
Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh ( mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

Abstract 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.

The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives —anthracite, dolomite —and binders are prepared in terms of particle size and chemical specifications, dosed, and mixed together to feed the pelletizing process;
The crushed iron ore is then processed above ground to either fines or iron ore pellets. It is a complex process that takes place in several stages: Sorting: The ore is roughly sorted and residual waste rock removed. After that, the iore ore is crushed into smaller fractions.
