Effect of organic binders on the activation and properties of indurated
In the ironmaking process, the addition of an organic binder to replace a portion of bentonite has the potential to improve the performance of pellets. The interaction between original bentonite (OB) and organic binder was investigated. Results indicated that the micromorphology of organic composite bentonite (OCB) became porous and the infrared difference spectrum …

Can fly-ash extend bentonite binder for iron ore agglomeration?
⋅ Iron ore pelletization with bentonite binder works by a different binding mechanism than with FBB. Bentonite is a physical binder, while FBB is a pozzolanic binder. ⋅ Iron ore concentrate pellets produced with up to 50% of the bentonite replaced by fly-ash exceeded minimum industrial specifications for dry compressive strength.

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.
