· The natural 2:1 clay mineral (two silica tetrahedral sheets and one alumina octahedral sheet) sample, selected for this study, is a natural bentonite clay. The natural bentonite clay samples were collected from Matrouh city, Egypt. The lump raw bentonite (500 g) was dried (70 ± 1 °C) in an air oven, crushed, ground, and sieved to fine powder (> 160 μm). The CEC of the sample was determined ...

· 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, suitable as feed material in blast furnaces for pig iron production, or in the production of direct reduction iron (DRI). Construction and Civil Engineering: Bentonite in civil engineering appliions is used traditionally as a ...
Bentonite is a multiuse clay generated from volcanic ash. They are considered predominantly in the smectite mineral family. This volcanic clay was formed millions of years ago when mineral sea deposits came in contact with the Earth's surface at incredibly high temperatures. The result created a magnetic charge, hence the alternative name "living clay." This magnetic charge creates a ...
Miocene Toledo Formation, in Balamban, Cebu Province, Philippines. Multiple analytical techniques reveal that the clay constitution of the bentonite is principally smectite minerals. Mixedlayer kaolinite/smectite is also indiive in some specimens. Xray diffractograms of untreated < 2 fi m fraction oriented samples show that the

Uses of Clay Pharmaceuticals/ Cosmetics: Bentonite is used as a binder in tablet manufacturing and in diarrhea mediions. Clays are used as thickeners in a wide variety of cosmetics including facial creams, lipsticks, shampoos and calamine lotion. Pelletizing: Bentonite is used to bind tiny particles of iron ore, which are then formed
Bentonite, a clay that is rich in smectites and formed by the alteration of volcanic ash, has various ratios of divalent and trivalent iron in nature and these are reflected as variations in the color of the bentonite clay from green or blue for divalent iron to grey or red for trivalent iron ( bentonite in Bavaria, Germany; South Dakota, USA; Milos, Greece).

Sodiumbased bentonite of 75 mm size finds suitability in iron ore palletization for bonding by user industries. Bentonite has also remarkable colloidal and waterproofing properties. Bentonite gels are used as a carrier for a number of cosmetic preparations, toothpastes, creams, etc. Bentonite is also used in chemical, rubber, insecticide pesticide industries and in civil construction works ...
Kurdjali town. The bentonite clays are formed in hydrothermal alteration of volcanic tuffs. They alternate by not altered tuffs in some areas in or around the deposit. The bentonite clays are covered by the products of the second acid lava pyroclastic horizon. The clays are green, grey greenish and yellow .

The invention relates to the production of activated bentonite clay drilling muds, foundry Sands and iron ore pellets. To activate bentonite clay is used, the substitution of the ions calcium, magnesium and iron ions of sodium, for which wet bentonite clay treated with sodium chemical (soda ash, caustic soda, trisodium phosphate and others).
Bentonite Clay For Iron Ore Pelletization at Rs 1000. 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.

Primarily two varieties of bentonite are available sodium bentonite (high swelling, gelling and thermal durability) and calcium bentonite (more commonly available worldwide but with less swelling). The main uses of bentonite are for drilling mud, binder ( foundrysand bond, iron ore pelletizer), purifier, absorbent ( pet litter), and as a groundwater barrier.
· On the other hand, bentonite clay also exhibits ionic exchange, sorption and intercalation as the main reactions leading to the removal of turbid materials/heavy metals [52, 53]. The mineralogy of the AMD, pH and conductivity of the AMD sample, treated with a combination of bentonite clay and Na 2 CO 3 with mixing is shown in Figure 5.
