In the production of iron ore concentrate pellets, binders are required to improve pellet green strength. The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% by weight of moist concentrate. Bentonite is a significant cost item in iron ore pelletization, and also contributes …

The work discussed a technology for iron ore agglomeration, where a mixed charge was humidified up to 6–10% with a pulp containing bentonite with a particle size of no more than 0.1mm and consumption of 2–18 kg/t. This resulted in an increased impact strength of the obtained agglomerate and its reduced resistance to abrasion.

One binder that is widely used in the production of iron-ore pellets is bentonite. The main mineral in bentonite – montmorillonite – has a unique ability to absorb water and undergoes a significant increase in volume. This phenomenon is called swelling . Study of the kinetics of swelling shows that this process is near completion after 24 h.
