Bentonite has proven to be an invaluable asset in the water treatment industry. Its adsorption capabilities, ion exchange mechanism, and various advantages make it an effective solution for the removal of contaminants and impurities from both drinking water and wastewater. However, it is essential to optimize dosage, address …
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 …
To improve the ballability of iron concentrates and enhance the performance of green balls and dry pellets in the production of iron ore pelletizing, the bentonite was usually used as a binder in the pelletizing process [].Bentonite, a very important nonmetallic mineral, is mainly composed of montmorillonite [2, 3], which is an aqueous …
This study illustrates the feasibility of pelletizing magnetite iron ore concentrate using four organic binders: KemPel, Alcotac CS, Alcotac FE16, and CMC, in comparison to bentonite as a reference.
One binder that is widely used in the production of iron-ore pellets is bentonite. The main mineral in bentonite – montmorillonite – has a unique ability to absorb water and undergoes a significant increase in volume. This phenomenon is called swelling . Study of the kinetics of swelling shows that this process is near completion after 24 h.

Bentonite layers from an ancient deposit of weathered volcanic ash tuff in Wyoming Gray shale and bentonites (Benton Shale; Colorado Springs, Colorado). Bentonite (/ ˈ b ɛ n t ə n aɪ t / BEN-tə-nyte) is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite.Na …
The binder is an essential auxiliary material in the production of iron ore pellets as it controls the properties of both green and hardened pellets [6]. Currently, …
The role of chemical reagents to reduce moisture in iron ore fines is explored in the present work which includes ionic and non-ionic surfactants. The washing of iron …
The most popular binder for this purpose is bentonite clay, which is added at a rate of approximately 0.5–1.0% 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. If the binding effectiveness of bentonite is increased, it ...
This study illustrates the feasibility of pelletizing magnetite iron ore concentrate using four organic binders: KemPel, Alcotac CS, Alcotac FE16, and CMC, in comparison to bentonite as a reference.
This technique has become viable with recent advances in large-scale material dewatering technologies. The present study seeks to evaluate the mechanical behaviour of cemented iron ore tailings comparing the yield of a commercial binding agent (Portland cement - PC) and an alternative binder (alkali-activated cement - AAC).
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron …

Bentonite solutions have viscous, variable, and lubricant properties. Different types of bentonites influence pellet properties, as well as the interaction among heterogeneous or homogeneous bentonites and iron concentrate [ 3 – 6 ]. In this study, we utilized three different types of bentonites for a pelletizing test.
