2018-11-9  What is Bentonite Clay. Bentonite clay is derived from the weathering of the volcanic ash. The clay mostly consists montmorillonite. Though there are various types of this clay, the two main classified are Calcium and Sodium Bentonite. Mining and Processing. The deposits of this clay are found in many countries including very large in the USA.

Bentonite Minerals Technologies Inc.

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.

2012-1-4  Bentonite Mines USA During the Cretaceous, volcanoes in the Yellowstone area of Wyoming were subject to long periods of eruptions. Ash falling from these eruptions dropped into seas which covered much of Wyoming, forming a sediment as much as 50 feet deep. These sediments were slowly altered into the clay known as bentonite.

Bentonite an overview ScienceDirect Topics

Bentonite is an absorbent natural smectite clay. It has a colloidal structure in water. Each smectite particle is composed of thousands of submicroscopic platelets stacked in a sandwich fashion with a layer of water between each. A single platelet is 1 nm thick and up to several 100 nm across.

The bentonite clay is often extracted from open pit mines with different deposit depths and many impur-ities. Therefore, bentonite purification is an important process, which is an expensive and complex procedure for separation of montmorillonite.

Bentonite an overview ScienceDirect Topics

Bentonite is an off-white montmorillonite clay formed from altered volcanic ash. It has a sheet-silicate structure and is especially notable for the way in which it absorbs and loses water and for its base-exchange properties. Sodic bentonite can absorb up to 10 times its own weight in water and can swell to 18 times its dry volume.
