The purpose of the iron pelletizing process is to convert the iron-rich fine-grained minerals into blast furnace charging material, which is defined as pellet, through agglomeration and hardening. The pellets are rigid and generally spherical shape and must have the following properties to be used in the high-temperature furnace:

Review of organic binders for iron ore concentrate agglomeration

Low-grade iron ores are finely ground and processed to recover iron-bearing minerals. However, the iron-rich powder is too fine to be used directly in blast furnaces and most direct reduction furnaces, and must be agglomerated or pelletized into a usable product called "pellets." Bentonite clay has traditionally been used as a binder to make …
