(NewsTarget) The healing bentonite clay derived from the montmorillonite family is a volcanic ash that has fallen into prehistoric bodies of water. As these bodies of water evaporate they leave behind a bed of mineral rich bentonite clay.

Abstract — In the use of bentonite in different industrial applications, different additives are recommended to optimize the rheological properties of the formulation.

The most important properties of bentonite for which it is employed in many different industries are the following: Water absorption and swelling A fundamental property of bentonite is to absorb water and expand. However, not all bentonites have the same absorption capacity.

Sodian Bentonite: A high sodium variety of bentonite. alkaline-earth bentonite: A bentonite containing easily exchangeable alkaline-earth cations and, either before or after acid treatment, capable of being made to assume properties of an alkali bentonite by treatment with an alkali salt followed by regulated dialysis.

Bentonite clay is composed dominantly of the clay mineral smectite. Its physical properties and characteristics are dictated by this clay mineral (Wright, 1968). In the majority of cases bentonites are formed by the alteration of volcanic ash and rocks after intense contact to water.

Two distinct types of bentonite are (1) Wyoming and South Dakota deposits referred to as sodium montmorillonite having high gelling, swelling, and viscosity properties and (2) Mississippi bentonite referred to as calcium montmorillonite with little or no swelling capacity.

This chapter discusses the properties and uses of bentonite. Bentonites have a variety of uses in various industries. The properties of bentonites are contingent upon the fact that they are composed of smectite clay minerals, and the properties of the smectite in turn are contingent upon its chemical composition, atomic structure, and morphology.
