Six Stages. One Outcome:
99.99% SiO₂.
Mine to mill to port. Full supply chain transparency.
Primary Crushing
Raw quartz ore is fed into primary and secondary crushers, reducing run-of-mine material to 5–10mm. Screening efficiency exceeds 90%, ensuring consistent feed size for subsequent grinding stages.
Grinding & Classification
Jaw-crushed material enters rod mills and ball mills for precision size reduction to 20 mesh, 100 mesh, or custom micron targets. Classification circuits separate on-spec material from oversize, which is returned for re-grinding.
Physical Purification
Attrition scrubbers agitate quartz particles under high-density slurry conditions, stripping clay coatings, iron staining, and fine mud inclusions from particle surfaces. Desliming circuits remove sub-10-micron fines before downstream processing.
Magnetic Separation
High-intensity magnetic separators remove paramagnetic iron-bearing minerals including hematite, goethite, and iron-stained inclusion particles. This stage is critical for meeting Fe₂O₃ specifications required by photovoltaic and optical fiber applications.
Flotation
Froth flotation with selective collectors removes residual non-magnetic silicate impurities including mica, feldspar, and chlorite. The process uses non-toxic reagents with full effluent treatment before discharge.
Chemical Purification
Controlled acid leaching with dilute HCl and HF dissolves residual metallic oxide inclusions from grain surfaces and intracrystalline fluid inclusions. Post-acid washing with deionized water and drying brings the material to specification for semiconductor-grade and optical applications.
