Mineral information

LKAB Minerals offer a range of products with varying Montmorillonite content dependent upon the end-user. You will find more information on the chemistry and physical properties of our product definition, which you can request from your local sales manager.

Mineral origin

Bentonite is derived from volcanic ash and consists predominately of smectite minerals, usually Montmorillonite. We categorise this product as a sedimentary deposit containing >50% Montmorillonite which is volcanic in origin. Montmorillonite is a dioctahedral layer silicate, and in sodium form swells when mixed with water to form dispersed colloid-size particles.
There are two common types of Bentonite for commercial use; sodium (or swelling) Bentonite and calcium Bentonite.

Toxicology

Bentonite is non-toxic and inert. LKAB Minerals do not offer this product for consumption in any form.

Industry use

Our customers use industrial minerals to improve constructions, increase safety and reduce costs.
