Specification first
We start from your process requirement and work back to the right grade, rather than selling what happens to be in stock.
About Us
Geological precision, engineered for industry.
Obsidian Minerals is a manufacturer and exporter of industrial minerals and specialty chemicals, headquartered in Bhavnagar, Gujarat — one of India's most important mineral belts.
Who we are
From proven deposits to precise specifications
We source minerals from proven geological deposits across Gujarat, Rajasthan, Madhya Pradesh and Tamil Nadu and process them into consistent, application-specific grades. Our portfolio spans 16 products — from API 13A drilling clays and foundry bentonite to bleaching earth, carbonates and magnesium chemicals — supplied in 54 defined grades.
Every grade is built around the parameter that matters to the customer: viscosity yield for a mud engineer, bleaching activity for a refinery, green compression strength for a foundry, brightness and particle size for a coatings formulator. We control those parameters through selective mining, drying, milling, air classification and, where needed, activation or surface treatment.
Our customers include manufacturers, distributors and importers in more than 15 countries. They choose us for consistent quality, responsive technical support and documentation they can rely on.
How we work
Consistency over time
Lot-to-lot repeatability is checked against retained samples so your production line sees the same material every delivery.
Transparent documentation
TDS, MSDS and a batch Certificate of Analysis accompany every shipment, so incoming QC can release material quickly.
Responsible operations
Land reclamation, dust control and community investment are part of how we run our mining and processing sites.
ISO 9001 certified processes
NABL-accredited lab testing
CoA, TDS & MSDS with every shipment
Export packaging worldwide
