ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE .
Bentonite is the most widely used binder in iron ore pelletizing. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet qualities, however, because of its acid constituents (SiO 2 and Al 2 O 3) it is considered as an chemical impurity especially for concentrate with high SiO 2 content. These acid oxides are known for their adverse effects on the ironsteel ...

A bentonite binder composition and method of preparation is disclosed. The binder composition is particularly useful for pelletizing iron ore fines. It is prepared by intimately combining and mixing wet bentonite in a stockpile with soda ash, the moisture in the wet bentonite bringing about reaction to form an improved binder after a suitable aging period.
