Executive Summary
As a trusted processor of 4,500 MT of quartz grit per month, we deliver high-brightness, low-contamination raw materials tailored specifically for engineered slab production. Our cutting-edge processing ensures:
✔ 99.5–99.9% SiO₂ purity (Fe₂O₃ < 0.015%)
✔ High End processing & AI-based sorting to eliminate silica dust risks
✔ Custom particle engineering (0.1mm–6mm)
✔ Ethical mining practices with carbon-neutral operations
Our Commitment to Compliance & Sustainability
We stay ahead by aligning with evolving industry standards:
- Secured mining permits (India’s DMG approval, Vietnam export licenses)
- Transitioned to wet processing to reduce dust hazards
- Implementing advanced dust control technologies (cyclone filters, closed-loop systems)
- Secured legal mining rights (India/AP government approvals)
- Supplying low-iron grit (< 0.01% Fe₂O₃) for premium slab applications
- Partnering with recyclers to meet the rising demand for “green quartz”
Technical Specifications for Slab Manufacturers
| Grade | Size Range | Brightness (ISO %) | Key Slab Applications |
|---|---|---|---|
| Ultra White | 0.1–0.4 mm | 93–94% | High-Gloss and Polished Slabs |
| Super White | 0.3–0.7 mm | 92–94% | Surface veining, high-end slabs |
| Standard Core | 1.2–2.5 mm | 88–90% | Base layers in slabs |
| Ultra-Fine | 325–500 mesh | 95–97% | Coatings, additives |
Customized Grit Sizes for Luxurious Slab Designs
At Nemmali Minings, we understand that premium slab manufacturing requires precision and flexibility. That's why we tailor specific quartz grit sizes to meet your unique design needs:
0.1–0.2 mm Grits: Crafted for creating bespoke, luxurious slab finishes with ultra-fine, reflective particles that elevate surface elegance and depth. Perfect for high-end coatings, intricate inlays, and polished surfaces.
2.5–4 mm & 4–6 mm Grits: Processed in our dedicated sieving facilities, these larger-sized grits enable textured, bold veining and natural stone effects, giving your slabs distinctive character and visual impact.
Quality Certifications
ISO 9001 certified
Bulk density: 1.55–1.65 g/cm³
