What is sodium bentonite used for?

Sodium bentonite is a swelling clay used across heavy industry. Its main applications are foundry green-sand molding, water-based drilling muds (API spec), iron ore pelletizing, civil engineering and waterproofing, animal feed binding, mycotoxin adsorption, cat litter, edible-oil bleaching, ceramic body formulation, and cosmetics.

What grades of bentonite does Clay Bentonite supply?

Clay Bentonite supplies eleven grades across six application categories: foundry bentonite (green-sand molding), API drilling bentonite (water-based muds and HDD), animal feed bentonite, cat litter bentonite (clumping), activated bleaching earth (oil refining), ceramic-grade white bentonite, and bentonite granules for industrial use. Custom specifications are available.

What are the typical specifications of Clay Bentonite sodium bentonite?

Typical specifications: minimum 82% montmorillonite by XRD, 28 ml swelling index per 2g sample, pH 9.2 ± 0.4 in 5% slurry, 3.4 N/cm² wet tensile (DIN 18132), 220 kPa green compression at 4% addition, 95% pass −200 mesh, maximum 12% moisture at delivery.

How is Clay Bentonite bentonite shipped?

Standard packaging is big bags up to 1,000 kg, loaded into 20-foot dry shipping containers. Other packaging configurations including private-label retail packs are available for cat litter and consumer products.

Who founded Clay Bentonite LLC and how long have they been in business?

Clay Bentonite LLC is a producer and miner of sodium bentonite. The team has 25+ years of mining experience in the South Caucasus and West Asia region.

Producer and Miner of Bentonite Clay

A clay,
two million years
in the making.

Bentonite is a soft plastic clay consisting predominantly of montmorillonite, formed through the slow alteration of volcanic ash. Its swelling, viscosity, and adsorption properties make it indispensable across foundry casting, drilling muds, animal feed, pet litter, civil engineering, and oil refining.

We operate mining and production facilities, supplying high-quality white bentonite to industrial buyers worldwide. Our qualified staff bring more than 25 years of mining experience to every shipment.
