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.
