Iron Ore Pelletizing Bentonite

Iron Ore Pelletizing . Bentonite is commonly used in pelleting of iron ore. The use of bentonite as binding agent is quite common in the world due to its availability and its being cheap. Montmorillonite montmorillonite (Al, Mg)2 (OH)2 (Si, Al)4 O10 n. H2O, which the main mineral of bentonite, is fine grained. Specific surface area reaches up to 10.000 cm2/gr. Natural bentonite is comprised of

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 iron-steel

ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE PELLETIZING

The use of conventional bentonite binder is favorable in terms of mechanical and metallurgical pellet properties, however, because of its acid constituents bentonite is considered as impurity especially for iron ores with high acidic content. Therefore, alternative binders to bentonite have been tested. Organic binders are the most studied binders and they yield pellets with good wet strength

Iron Ore Pelletizing Process: An Overview IntechOpen

11/07/2018 Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing. Despite its low cost, the inorganic compounds from bentonite are contaminants increasing the
