Pelletisation of iron ore is one of the key uses for bentonite clays in refractories without coal. The bentonite is employed as a flux, making firing a less energy intensive process, and allows for the oxidation of magnetite to hematite ahead of the blast furnace(16).
The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). The main uses of bentonite are for drilling mud, binder (e.g. foundry-sand bond, iron ore pelletizer), purifier, absorbent (e.g. pet litter), and as a groundwater barrier.
Calcium bentonite has a higher green strength, lower dry strength, lower hot strength, and better flowability than sodium bentonite. Methods of testing sand–clay mixtures are outlined in publications of the American Foundrymen's Society (Anonymous, 1963). 3. Pelletizing iron ore. Sodium bentonite is used to pelletize iron ore (Devaney, 1956 .
Oct 18, 2018 · In the work of mechanical casting and iron ore pellets, the requirements for expansion are high. A large amount of calcareous bentonite does not meet the requirements for use, so it is necessary to modify the calcium bentonite before use. The dispersion of sodium bentonite is higher than that of calcareous bentonite.
it would be nearly impossible to agglomerate iron ore using rotary drums and discs without using a binder. Eisele and Kawatra (2003) reviewed every binder type that had been tested for iron ore agglomeration and concluded that inorganic bentonite clay "is still the dominant binder",
⋅ 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 fly-ash exceeded minimum industrial specifications for dry compressive strength.
Bentonite - Wikipedia
Bentonite has been widely used as a foundry-sand bond in iron and steel foundries. Sodium bentonite is most commonly used for large castings that use dry molds, while calcium bentonite is more commonly used for smaller castings that use "green" or wet molds. Bentonite is also used as a binding agent in the manufacture of iron ore (taconite .

Bentonite clay is also used in pyrotechnics, to make end plugs and rocket engine nozzles. Bentonite has remarkable colloidal and waterproofing properties. Bentonite gels are used as a carrier for a .
Bentonite is used for 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. Through this process, iron ore fines are converted into spherical pellets .
Bentonite is commonly used in pelletting of iron ore. Bentonite plays an important role in using degradable iron ores with low grades upon pelleting. While activated calcium bentonites swell about
Bentonite and calcium hydroxide are the widely used binding materials in iron ore pelletizing plants. This investigation deals with studying the effect of using a mixture of both binders on the .
The results of these analyses showed that pyrite ash can be agglomerated to pellets and used in the iron production industry as a blast furnace feed. The crushing strength of the pellets containing calcium hydroxide and calcium chloride in addition to bentonite was better than the strength of pellets prepared using only bentonite binder.
Abstract: Sodium-activated 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. In this article, the microstructure of bentonite in magnetite pellets is revealed for the first time using scanning electron microscopy. The microstructure of bentonite in wet
