General introduction

Bentonite is a type of clay that generated frequently from the alteration of volcanic ash, consisting predominantly of smectite minerals, usually montmorillonite. It usually forms from weathering of volcanic ash in seawater, which converts the volcanic glass present in the ash to clay minerals. One of the first findings of bentonite was in the Cretaceous Benton Shale near Rock River, Wyoming. The Fort Benton Group, along with others in stratigraphic succession, was named after Fort Benton, Montana, in the mid-19th century by Fielding Bradford Meek and F. V. Hayden of the U.S. Geological Survey. Bentonite has since been found in many other locations, including Spain and India.

Bentonite is a finely powdered, odorless, and the colors could be various from yellowish, creamy, greyish to white. Bentonite is insoluble, but dispersible in water. Bentonite presents strong colloidal properties and its volume increases several times when coming into contact with water, creating a gelatinous and viscous fluid. The special properties of bentonite (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications.


According to the final application, bentonite is either sieved (granular form) or milled (into powder and super fine powder form). For special applications, bentonite is purified by removing the associated gangue minerals, or treated with acids to produce acid-activated bentonite (bleaching earths), or treated with organics to produce organoclays.

The applications of Bentonite are various, including: Foundry, Pelletizing, Drilling, Agriculture, Construction and Civil Engineering, Environmental markets, Detergents, Paints, Cat litter and the highest quality Bentonite could be used in manufacturing Cosmetics and Pharmaceuticals.
