Iron Ore Pelletization: Part I. Fundamentals | Semantic Scholar
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. Meeting these requirements leads to the formation of strong …

Humic Substance-based Binder In Iron Ore Pelletization: A …
ABSTRACT Due to the reducing ability and bonding effect, a humic substance-based binder has been added into iron ore pellets, both as a reductant and a binder. However, humic substance-based binders were not commonly used in pelletization since some pelletizing results indicated they were not as good asbentonite or other binders. Thus, there were few …

ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE
Bentonite clay is the most widely used binder for iron ore pelletising as it can achieve both functions (Kawatra and Claremboux, 2022b). However, it is an inorganic compound that primarily ...
The role of normal and activated bentonite on the pelletization …
The investigation was also carried out on the utilization of both activated bentonite and sodium-based bentonite as a binder for pelletization of high-grade barite iron ore concentrate. The quality and the average strength of the sodium-based bentonite were found higher than that of the activated bentonite being used [14].

New Paradigms for Iron Ore Pelletization | SpringerLink
Yet, bentonite does not undergo any such chemical reactions within pellets. Instead, bentonite physically binds to iron ore particles. Bentonite additionally controls excess water within the pellet. Sodium bentonite in particular can absorb around 900% PWA, allowing pelletization moistures to remain considerably more consistent than without binder.
