Bentonite is the most widely used binder in iron ore pelletizing industry. The use of bentonite is favorable in terms of physical, mechanical and metallurgical pellet properties, however, because of its acid constituents (SiO2 and Al2O3) it is considered as a chemical impurity especially for concentrate with high acidic content.

compared with the bentonitebonded pellets. Hence, the suggested combined binders can be used as binder in place of bentonite in iron ore pelletizing without compromising the pellet chemistry. KEYWORDS: iron ore pelletizing, bentonite organic binder, boron compounds, colemanite, chemical and metallurgical properties.
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).
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. It .
Due to bentonite's water absorption capacity and colloidal properties, bentonite is used as binding additives to convert iron ore fines to pallets. Fine powder helps in to develop good strength pallets. Even at lower additions develops excellent green and dry ball strength. Better binding strength is maintained before and after firing of pallets.
The term Bentonite was first used for a clay found in about 1890 in upper cretaceous tuff near Fort Benton, Wyoming. The main constituent, which is the determinant factor in the clay's properties, is the clay mineral montmorillonite. Iron Ore. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are ...
Bentonite is composed of plate silicate minerals and belongs to the smectite clay group. It is high swelling clay generated casually from the alteration of volcanic ash and consistently predominantly of smectite minerals. Bentonite is clay formed by the alteration of volcanic ash deposits, mostly in upper Cretaceous formations.
Sodiumactivated calcium bentonite is used as a binder in iron ore pellets and is known to increase strength of both wet and dry iron ore green pellets.
The binding properties of bentonite are utilised for the pelletising of fine iron ore concentrates to be used in blast furnace operations and steel smelting. In the huge consumer market of pet litter materials, clump formation in contact to water makes bentonite ideally suited for this application.
Bentonite having low iron content is found to be good catalytic agents in the petroleum refining process. In comparison to plastic clay, bentonite can absorb higher amounts of water, thus helping in the grouting of wells, dams and drilling muds.

Bentonite is also used as a binding agent in the manufacture of iron ore pellets as used in the steelmaking industry. Bentonite, in small percentages, is used as an ingredient in commercially designed clay bodies and ceramic glazes. The ionic surface of bentonite has a useful property in making a sticky coating on sand grains.
