Abstract. Bentonite is the most commonly used binder for iron ore pellets. However, due to its high alumina and silica content, the slag volume and energy consumption are increased. The aim of the present work is to identify the CSL (sodium ligninsulfonate added CaCO 3) as an alternative binder in iron ore pelletization. FTIR

This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum utilization of iron ore. ... The next step involves grinding this dried residue, with the addition of Bentonite which is a ...
The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:
Based on the investigation on the influence factors of the humic substance adsorption onto the iron ore surface and the pelletization of iron ore concentrates with humic substance-based an binders, the relative viscosity of a humic substance-based binder can be used as an indicator of the morphology of the humic substance or as an index of ...

During iron ore agglomeration or pelletization, moist iron concentrate particles and flux materials are rolled into balls with the aid of a binder (Figure 1). Balls tumble and grow in rotating drums and discs. While ... example, with bentonite, it is well known that using a western, or Wyoming, bentonite with high ...
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 ...
A bentonite has been using as a binder to iron ore pelletization from very beginning. It gives excellent binding property to green and dry pellet properties. However several drawbacks of bentonite have been observed such as an impurity due to its ... The microstructure of bentonite in wet and dry iron ore pellets, as well as in distilled water ...
Keywords: HA, modified bentonite, characterization, iron ore, pelletization Abstract A new kind of iron ore pellet binder named humic acid modifying bentonite (HA-) has been developed by the author's group, which has the advantages of both organic HA and inorganic bentonite. The green pellet strength can be obviously improved by

Iron ores can be classified as high grade and low grade in terms of their Fe content. High grade iron ores which can be
Inorganic binders like bentonite, used for pelletization of low-grade iron ore, generate iron ore slimes with comparatively high silica and alumina content necessitating extra steps for their removal during iron making process. This demands the usage of organic binders as full or partial replacement of bentonite for iron ore …
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
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 …
Although bentonite clay is the most commonly used binder, there are many other possibilities that could be competitive in a number of situations. This article reviews the numerous types of binders (both organic and inorganic) that have been considered for iron ore pelletization, including discussion of the binding mechanisms, advantages and ...

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.
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).
