The classically accepted mechanism for binding fine iron ore concentrates by bentonite clay is that the clay becomes hydrated, expands, disperses, and then dries into a bonding film that holds the ...
Bentonite has been called "Miracle Mud" and the "Clay of a Thousand Uses." Some of these include absorbents, animal feed, drilling fluids, foundry, iron ore pelletizing, and sealants. Wyoming bentonite is particularly in demand for pet litter because of it''s ability to absorb many times its .
In the production of iron ore concentrate pellets, binders are required to improve pellet green strength, the most popular binder for this purpose is Sodium Bentonite clay which has higher water plate absorption along with superior thermal stability.
Dec 01, 2000· ⋅ Iron ore pelletization with bentonite binder works by a different binding mechanism than with FBB. Bentonite is a physical binder, while FBB is a pozzolanic binder. ⋅ Iron ore concentrate pellets produced with up to 50% of the bentonite replaced by flyash exceeded minimum industrial specifications for dry compressive strength.
Bentonite is a hydrated clay mineral with montmorillonite as its main constituent. ... S. K. Kawatra and S. J. Ripke, "Effects of bentonite fiber formation in iron ore pelletization," International Journal of Mineral Processing, vol. 65, no. 34, pp. 141–149, 2002.
The microstructure of bentonite in wet and dry iron ore pellets, as well as in distilled water, was imaged by various imaging techniques (, imaging at low voltage with monochromatic and decelerated beam or low loss backscattered electrons) and cryogenic methods (, high pressure freezing and plunge freezing in liquid ethane).
To process taconite, the ore is ground into a fine powder, the iron is separated from the waste rock by using strong magnets, and then the powdered iron concentrate is combined with bentonite clay and limestone as a flux and rolled into pellets about one centimeter in diameter that are approximately 65% iron.
A bentonite binder composition and method of preparation is disclosed. The binder composition is particularly useful for pelletizing iron ore fines. It is prepared by intimately combining and mixing wet bentonite in a stockpile with soda ash, the moisture in the wet bentonite bringing about reaction to form an improved binder after a suitable aging period.

Bentonite for ironore pelletizing | Bentonite. While interacting with the water, bentonite clay expands and becomes sticky. This property allows to effectively use it as a binder for the production of pellets from iron ore concentrate (wet, crushed iron ore that has been beneficiated).. Pellets are used in blastfurnace redistribution and .
Bentonite is a clay generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite. ... 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).
Bentonite is the commercial name of a whole range of natural clays with a high water absorption capacity causing it to expand and swell. APPLICATIONS Foundry, Drilling, Civil engineering, Feedstuff, Water treatment, Agriculture, Ceramics, Paper, Wine making, Cat litter, Pelletizing of iron ore, Pharmaceuticals, cosmetics, and spa mud therapy ...
Bentonite is formed from the alteration of volcanic ash. Bentonite is used in pet litter to absorb liquids. It is used as a mud in drilling applications. It is also used in other industrial applications such as the "pelletizing" of iron ore. Common clay is used to make construction materials such as bricks, cement, and lightweight aggregates.
Bentonite is used for cat litter, due to its advantage of absorbing refuse by forming clumps (which can be easily removed) leaving the remaining product intact for further use. Pelletizing. Bentonite is used as a binding agent in the production of iron ore pellets.
Not only is bentonite the clay of 1,000 uses it also comes in many colors. Bentonite clay has been on the FDA''s GRAS list (Generally Recognized as Safe) for many years.
