High SiO2 quartz lumps and silica grains for glass, ceramics, and semiconductor industries.
Golden I Minerals extracts and processes exceptionally pure crystalline quartz, characterized by an exceptionally high silica (SiO2) content and ultra-low iron levels. This makes it an indispensable raw material for high-end industrial and technological applications.
Through precision sorting, magnetic separation, and fine milling, we produce glass and ceramic grade quartz that delivers superior thermal resistance, electrical insulation, and brilliant whiteness.
We offer diverse grades of quartz meticulously prepared to meet specific industry tolerances:
| Parameter | Standard Value |
|---|---|
| Silica (SiO2) | 99.2% - 99.8% |
| Iron Oxide (Fe2O3) | < 0.015% |
| Alumina (Al2O3) | < 0.2% |
| Whiteness Index | 90% - 95% |
| Available Mesh Sizes | 30 to 325 Mesh |
| Forms Available | Lumps / Granules / Powder |
The exceptional purity of our quartz makes it essential for advanced manufacturing:
Hand-sorted, high-purity crystalline lumps used primarily for metallurgical smelting.
Clean, precisely sized grit utilized in engineered stone and glass manufacturing.
Fine milled powder (up to 325 mesh) crucial for ceramic glazes and fiberglass.
Ultra-high purity processed quartz tailored specifically for the semiconductor industry.
Iron contamination is the enemy of high-grade quartz applications like glassmaking. To achieve iron levels below 0.015%, our processing plants utilize multi-stage high-intensity magnetic separators.
Coupled with rigorous optical sorting and continuous spectrographic analysis in our NABL labs, we guarantee a mineral product that offers perfect whiteness and optical clarity for our most demanding global clients.
