The iron ore pelletization is the process of converting iron fines less than 200 mesh (0.074 mm) into 8-16 mm pellets. Types of iron ore pellets Iron ore pellets are normally produced in two types of quality grades: DRI grade and BF grade. DRI pellets have a higher quality requirement, containing more than 67% iron content.

A full-scale plant trial of the substitution of a specific organic binder for bentonite was conducted in the company's straight grate pellet plant in Quebec, which produces 9.3 Mtpa of pellets, 36% of which are used as feedstock for the DR process. The results of the full-scale pellet plant trial are given in Table 15.13.
ABSTRACT. The behavior of iron ore pellet binders is complex. 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 inter-particle bonding within the pellet.
Usually, Iron Ore is manufactured and converted into Pellets. These are oval lumps of iron ore that are hardened using fuel. This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum ...
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. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …
This process will be discussed in more detail in the next section. In the direct-reduced iron (DRI) process, the iron ores are reduced directly to sponge iron by gaseous reducing agents!
