Bentonite is the traditionally used binder in iron ore pelletization. However, it consists of up to 85% silica and alumina which are undesired acidic gangue in iron-making.
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 ...
Yet, bentonite does not undergo any such chemical reactions within pellets. Instead, bentonite physically binds to iron ore particles. Bentonite additionally controls excess water within the pellet. Sodium bentonite in particular can absorb around 900% PWA, allowing pelletization moistures to remain considerably more consistent than …

GIMBOND ® is natural high swelling sodium based bentonite of exceptional purity. It is mined and processed in North West part of India. GIMBOND ® is sodium activated bentonite designed to meet the requirements of pelletization industries. GIMBOND ® is used as green and dry ore binder for all kind of pellets. GIMBOND ® offers superior …
ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet. Meeting these requirements …

Introduction Iron ore pelletization plants in the United States used approximately 612,000 metric tons of bentonite as a binder to produce iron ore concentrate pellets in 2000 (Virta, 2001). It is a major cost item, with individual plants spending US$3 – 5 million annually * Corresponding author.

FLOFORM™ Iron Ore Pelletization FLOFORM™, an alternative Traditionally bentonite is used as binder, but it reintroduces deleterious elements such as silica and alumina. FLOFORM is typically dosed at 0.01-0.05% prior to balling, i.e. about 1/20th of Bentonite. Depending on the quality of iron ore, a dual binder system comprising both
1. Introduction. Bentonite is the conventional binder in iron ore pelletization and used at 0.5–1.5% addition levels in the pellet feed by weight of iron ore [1], [2], [3].It controls the moisture of iron ore concentrate in the pellet feed and improves physical properties of the wet, dry, pre-heated and fired pellets.
The most common agglomeration technology in the iron ore industry is pelletization with bentonite being the most often used binder. The addition of very small amounts of Alcotac ® CS allows to reduce the dosage of bentonite by about 50% or more - without compromising on pellet quality. Depending on the quality of the bentonite and ore, …
The transformation from traditional iron- and steelmaking technologies to green H2-based new technologies will require an improvement in the quality and purity of iron ore burden materials. Iron ore pellets are essential inputs for producing direct reduced iron (DRI), but the conventional binders, used in iron ore pelletizing, introduce gangue …
Pelletizing iron ore fines is an agglomeration process that through a thermal treatment converts the ultra-fines fraction thereof into small balls ranging in size from 8mm (0.31 in.) to 18mm (0.71 in.), with adequate characteristics for feeding steel reduction works.

Bentonite is the most used binder in iron ore pelletization (Lu, et al., 2018). Bentonite is a clay mineral that consists mostly of silica (~65%) and alumina (~20 %) (Devasahayam, 2018).
Bentonite is the most common binder in iron ore pelletization. Bentonite has proven to be the most effective binder owing to its high water adsorption capacity and dry film strength. It is commonly used at an addition level of 0.5–1.5% by weight of iron ore. However, because of its acid constituents (SiO 2 and Al 2 O 3), it is considered as ...
