Bentonite. Bentonite is the common name for naturally occurring clay that contains the active montmorillonite mineral. The special properties of montmorillonite that enable commercial applications include the sub-micron platelet structure, very high surface area (≈ 800 m 2 /g), and inherent negative charge in the platelet that is counter balanced by exchangeable cations.
Bentonite originates from the in-situ weathering of volcanic ash and consists primarily of montmorillonite. Montmorillonite is a fine particle sized hydrous aluminium silicate and is one of the three layer clay materials. In the majority of cases, bentonites are formed by the alteration of volcanic ash and rocks after intense contact with water.

1. SUMMARY 1.1 Identity, physical and chemical properties, and analytical methods . Bentonite is a rock formed of highly colloidal and plastic clays composed mainly of montmorillonite, a clay mineral of the smectite group, and is produced by in situ devitrification of volcanic ash. In addition to montmorillonite, bentonite may contain feldspar, cristobalite, and crystalline quartz.
With its high adsorptive power, bentonite is the perfect environment friendly mineral for retention, dewatering, stickies control and water loop treatment. Bentonite consists of smectite clay minerals such as montmorillonite which are layered alumino-silicates that swell when in contact with water.
