Effects of bentonite fiber formation in iron ore pelletization
In the production of iron ore concentrate pellets, binders are required to improve pellet green strength. The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% by weight of moist concentrate. Bentonite is a significant cost item in iron ore pelletization, and also contributes In this work, a comparative study has been done to determine the effect of three different compositions of binders (bentonite and limestone (BLS), limestone and lime (LSL), and cement) and Blaine number on the properties of pellets prepared using the slime generated from the washing of Indian-origin iron ore.

IRON ORE PELLETIZING BENTONITE Bentonite
Bentonite is commonly used in pelletting of iron ore. Bentonite plays an important role in using degradable iron ores with low grades upon pelleting. While activated calcium bentonites swell about 5-6 times of their volume, Sodium bentonites can swell up to 25-30 times. Swelling is directly influenced by the Enslin value required for the pellet.it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder. Eisele and Kawatra (2003) reviewed every binder type that had been tested for iron ore agglomeration and concluded that inorganic bentonite clay “is still the dominant binder”,Review of Organic Binders for Iron Ore Agglomeration

Microstructure of Bentonite in Iron Ore Green Pellets
The microstructure of bentonite in wet and dry iron ore pellets, as well as in distilled water, was imaged by various imaging techniques (e.g., imaging at low voltage with monochromatic and decelerated beam or low loss backscattered electrons) and cryogenic methods (i.e., high pressure freezing and plunge freezing in liquid ethane).Bentonite is the most common binder in iron ore pelletization and used at 0.5-1.5% by weight.

Pelletizing
Pelletizing is the process of compressing or molding a material into the shape of a pellet. A wide range of different materials are pelletized including chemicals, iron ore, animal compound feed, plastics, waste materials, and more.The process is considered an excellent option for the storage and transport of said materials. The technology is widely used in The most commonly applied one is pelletizing in iron ore industry. Originally the pelletizing process was developed in the USA to treat the ultra-fine mineral dressing products obtained from the upgrading of Mesabi ore and has been utilized to provide a blast furnace feed product with Fe grade of about 65% (Ball et al., 1973).ALTERNATIVE BINDERS TO BENTONITE FOR IRON ORE PELLETIZING

The metallurgical and chemical tests results showed that good quality product pellets can be produced with combined binders when compared with the bentonite-bonded pellets. Hence, the suggested combined binders can be used as binder in place of bentonite in iron ore pelletizing without compromising the pellet chemistry.
