Mineral Description

Bentonite is an industrial clay rich in montmorillonite, known for its exceptional swelling capacity, absorption properties and rheological behavior. Bentonite is essential in drilling operations, construction, foundry applications, water treatment, agriculture and chemical processes.

Types of Bentonite

Sodium Bentonite: high swelling capacity, ideal for drilling and sealing.
Calcium Bentonite: excellent absorption and widely used in industrial formulations.

Industrial Uses and Applications

Drilling fluids: used as a viscosifier, stabilizer and filtration control agent.
Foundry: key component in high-strength molding sands.
Construction & geotechnical engineering: sealing of wells, waterproof barriers, tunnels and slurry walls.
Water treatment: natural adsorbent for metals and contaminants.
Agriculture: soil conditioner and nutrient carrier.
Food industry: clarifying agent and absorber.
Cosmetics: used in masks, detox products and personal care formulations.

Grades and Specifications

Available bentonite formats include:

Fine powder (50–200 mesh)
Granules
Activated bentonite
Drilling-grade bentonite
Foundry-grade bentonite

Extraction and Processing

Bentonite is extracted from open-pit mines and processed through drying, crushing, grinding, activation and particle-size classification. Chemical analysis includes montmorillonite content, CaO, Na₂O, SiO₂ and moisture.

Major producing regions include Pakistan, India, United States, Turkey, China and Greece.
