Pelletizing Bentonite is used as a binding agent in the production of iron ore pellets. Through this process iron ore fines are converted into spherical pellets suitable as feed material in blast furnaces for pig iron production or in the production of direct reduction iron DRI.
Jul 01 2002 The most popular binder for this purpose is bentonite clay which is added at a rate of approximately 0.51.0 by weight of moist concentrate. Bentonite is a significant cost item in iron ore pelletization and also contributes undesirable amounts of silica to the finished pellets.
The grade is also having higher natural percentage of Iron which is ideal in isolating ore pellets with the maximum percentages of Iron. The Iron Ore Pelletization plant can able to maintain active clay levels with reduced additions of Bentonite since IOP grade bentonite is having high Mont values.
Iron ore pellets use bentonite clay as binder at dosages of from 0.5 to 1.0 of the moist iron ore concentrate weight. As a natural product bentonite has variable water-absorption and binding .
Cat Litter Bentonite is used for cat litter due to its advantage of absorbing refuse by forming clumps which can be easily removed leaving the remaining product intact for further use. Pelletizing Bentonite is used as a binding agent in the production of iron ore pellets. Through this process iron ore fines are converted into spherical .
Iron Ore Pelletizing Bentonite 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.
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 Mg2 OH2 Si Al4 O10 n. H2O which the main mineral of bentonite is fine grained. Specific surface area reaches up to 10.000 cm2gr.
