The binding of iron oxide grains by bentonite clay to form pellets is a complex process, with a large number of variables, many of which have never been adequately studied. Current practice for pelletizing iron ore concentrates was developed in 1950''s during which bentonite clay was practiced as a binder and since then it has remained
Iron ore agglomeration is a wet process, where particles are held together by the surface tension and capillary forces when wet, they will fall apart upon drying unless binders are present. Most widely used binder is bentonite clay (ideally Sodium Montmorillonite), which has the disadvantage of increasing pellet silica and alumina
