Mineral Notes: Bentonite • Snowden

 · Bentonite is a clay consisting mainly of smectite minerals which are generally considered to have been formed by the alteration of volcanic ash. Bentonite deposits often occur as bedded deposits (e.g. western USA), though they may be irregular bodies associated with rhyolite or perlite / obsidian (e.g. China and Mozambique).

What is Bentonite Clay? + Dangers & How to Use

 · Components & How It Works. The main component is montmorillonite, a soft clay formed by layers of silica and alumina. Montmorillonite is normally bound to many clay minerals, especially sodium, calcium, magnesium, and aluminum [8, 3]. Bentonite may also contain small amounts of impurities such as other clays (illite, kaolinite) and crystalline silica (quartz, cristobalite).

Clay

The principal clay mineral composing bentonite is smectite. Smectite is most often used as a group name, encompassing a number of very fine grained minerals which possess certain ion-exchange characteristics. Bentonite''s commercial value is due to its ion-exchange ability, which determines the clay''s physical expansion and colloidal properties.
