Pelletizing iron ore. Sodium bentonite is used to pelletize iron ore (Devaney, 1956). Finely pulverized iron ore concentrates are pelletized into marble-sized spheres about 2.5 cm in diameter for ease of handling and shipping and to produce a superior furnace feed. The sodium bentonite constitutes about 0.5 wt.% of the pelletized ore.
This study suggests that bentonite application in semi-arid regions would have beneficial effects on crop growth and soil water-holding properties. ... Guiwei, Q., De Varennes, A. & Cunha-Queda, C ...
The elemental compositions of bentonite clay, date pit, and Cs-NP have been studied by EDX. The elemental composition of bentonite clay is shown in Fig. 4 and Table 3, which reveal that the dominant elements are O, Si, and Al in a percentage of 62.9, 28.05, and 10.22%, respectively, confirming the aluminosilicate structure . Na, Mg, K, Ca, and ...
bentonite, clay formed by the alteration of minute glass particles derived from volcanic ash. It was named for Fort Benton, Mont., near which it was discovered. The formation of bentonite involves the alteration of volcanic glass to clay minerals; this requires hydration (taking up or combination with water) and a loss of alkalies, bases, and ...
Modified bentonite. Bentonite, supplied by Sigma-Aldrich was applied as the raw precursor in this work. The acid modification was conducted by properly mixing bentonite with 8 M of nitric acid at ...
Topical application of bentonite clay has even been shown to help treat Buruli ulcers, ... Bentonite clay is used for hair conditioning and styling because its minerals help moisturize, soften and de-frizz hair, especially curly hair, according to anecdotal evidence.

La bentonite, qui est composée essentiellement de minéraux argileux appartenant au groupe des smectites, présente un grand domaine d'application en chimie et en industrie.
Proper storage of bentonite — much like filter pads — in a clean, dry environment and in a resealable container is crucial. Bentonite will absorb odors from the air, e.g. the cork taint component TCA, and release them into the treated wine. Waste issues Bentonite creates a solid waste problem if separated with the lees.
