Mineastra is a global supplier of industrial minerals from India, working closely with trusted partner mines and processing facilities to ensure a steady, scalable supply of Quartz, Feldspar, and Quartzite. We deliver across multiple grades — from high-purity quartz for electronics, glass, and solar applications to soda and potash feldspar for ceramics, tiles, and refractories. Every lot is carefully sourced, SGS/NABL tested, and fully documented, giving buyers complete confidence that their minerals meet international specifications and industry standards.

What truly sets Mineastra apart is our end-to-end supply chain integration. From mine-level procurement and grading, processing at modern screening plants, secure packaging, and port handling at Chennai, Krishnapatnam, and Mundra, every stage is managed with precision. This mines-to-ports control reduces uncertainty, ensures batch-to-batch consistency, and guarantees that shipments arrive on time, in full, and to exact buyer specifications.

With access to India’s richest quartz and feldspar belts, Mineastra is strategically positioned within the global silicon value chain — serving industries from glass and ceramics to solar and semiconductors. Whether you require bulk mineral supply contracts, containerized shipments, or tailored sourcing partnerships, we provide the scale, reliability, and future-ready vision your business demands.
