Bentonite is perhaps the most popular medicinal clay in use today. Discovered in 1898, its name comes from Benton Shale, which is a finegrained sedimentary rock found throughout parts of Wyoming, Montana, South Dakota, North Dakota, Nebraska, and Colorado. Bentonite clay is used mostly for drilling, construction, and other industrial purposes.

Platy soil structure and soil compaction (low porosity) impede gas flow, and a deficiency of oxygen may encourage anaerobic bacteria to reduce (strip oxygen) from nitrate NO 3 to the gases N 2, N 2 O, and NO, which are then lost to the atmosphere, thereby depleting the soil of nitrogen.
Bentonite clays have been planned to be used in various applications in order to backfill and seal the repository for high level spent nuclear fuel. The buffer around the waste canister composes of precompacted bentonite blocks while bentonite may also be used in backfilling and sealing of disposal tunnels and other underground facilities.

Benitoite and Neptunite Crystals: This specimen is a plate of translucent blue benitoite crystals and black neptunite crystals on a background of white natrolite. (This association is typical and an important characteristic of the mineral.) The crystals are about 2 centimeters in length and the plate measures about 15 x 11 x 2 centimeters in size.

structure [3,10,11]. As well, they are low cost and abundant around the world which makes them be a part of many industrial applications and in environmental control [10]. As well as in Egypt, bentonite, a naturally occurring clay, is considered a cheap adsorbent that has been used as an alternative material for the removal of dyes [11].
Jul 24, 2014· Bentonite clay is very effective and beneficial for your skin no matter what your age. What''s special about the bentonite clay mask is that it draws out toxins from the skin, shrinks your pores (noticeably just after a few uses), prevents breakouts, and leaves your skin soft and smooth.
Bentonite clay is a naturally occurring by product of volcanic ash exposed to wind and water.. It is added to natural body powders, usually in combination with corn starch or orris root powder. Moistened with a small amount of water, bentonite clay makes an excellent facial mask to .
Bentonite''s mechanism of action is physical, due to its colloidal structure and charged particles. The total adsorptive surface area of each tablespoon serving of Bentonite is over 900 square yards. The Bentonite is unique and naturally occurring with the proper mineral composition for maximum ability to remove unwanted substances.

In this study, the acidicmodified bentonite (AMB) was developed to enhance conditioning and dewatering processes of anaerobically digested sludge (ADS) for the first time and its performance was compared with inorganic salts, FeCl 3, AlCl 3, Al 2 (SO 4) 3 and Fe 2 (SO 4) structural changes were investigated employing XRD, XRF, FTIR and specific surface area tests.
Bentonite is an absorbent aluminium phyllosilicate generally impure clay consisting mostly of montmorillonite, (Na,Ca)(Al,Mg) 2Si4O10(OH)2·(H2O)n. Two types exist: swelling bentonite which is also called sodium bentonite and nonswelling bentonite or calcium bentonite.
