Bentonite

Bentonite is a highly absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. RMSPL, established in 2016 and headquartered in Bengaluru, partners with mine owners in Bhavnagar district (Gujarat) and Maharashtra to supply bentonite across India and for export.

Key Properties

• High swelling capacity and thixotropy in water
• Excellent binding agent for iron ore pelletization
• Superior viscosity control in drilling fluids
• Thermal stability for foundry moulding sands

Industries Served

Oil and gas drilling, iron ore pelletization, foundry and casting, civil engineering (bore piling, diaphragm walls), pharmaceutical, paper, paint, ceramic, animal feed, poultry, water well drilling, fertilizer, and cosmetics.

Products Offered

Product Form	Typical Application
Raw bentonite (lumps/chips)	Drilling, civil engineering, pellet plants
Bentonite powder (200 mesh)	Foundry, oil well, pharmaceutical
Bentonite granules	Fertilizer carrier, animal feed binder

Reference: Gujarat and Maharashtra are India's primary bentonite-producing states; montmorillonite content determines swelling index and API drilling grade compliance.
