  • (PDF) Hyperactivation of Bentonite in Pelletizing Process

    The replacement of bentonite as the standard iron ore binder is an important factor in the future of iron processing Bentonite adds unwanted silica to the final concentrated iron ore productSince the purpose of iron ore processing is to remove silicate minerals from the ore, adding silicates back in the form of binder is counterproductive This has prompted longterm interest in developing or discovering binders that contain no silica Therefore alternative binders to bentonite have been tested for many yearsALTERNATIVE BINDERS TO BENTONITE FOR IRON OREBentonite 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)Protech Minerals LLC | BENTONITE

    Iron ore pellets use bentonite clay as binder at dosages of from 05% to 10% of the moist iron ore concentrate weight As a natural product, bentonite has variable waterabsorption and binding properties depending on its source Therefore, it is best to have a method for evaluating a given bentonite to determine how effective it would be before it is purchased for use to bind concentrate intoWhile bentonite produces a physical bonding between iron ore concentrate grains in the pellet, the fly ash undergoes a pozzolanic reaction to form a cementitious bond between the particles The reaction between aluminosilicates of fly ash in the presence of water and lime will be as follows [ 2 ]:Usage of Fly Ash as Binder in Micropelletization ProcessIron Ore Processing for the Blast Furnace (Courtesy of the National Steel Pellet Company) there to a conveyor where bentonite, a bonding agent, is added Bentonite is a clay from Wyoming used to help iron ore concentrate stick together when rolled into pellets About 16 pounds of Bentonite are added to every ton of iron oreIron Ore Processing Welding Handbook
