Snow White Quartz Powder — The World's Most Demanded High-Brightness Silica

Snow White Quartz Powder — commercially known as Snow White Silica Powder, Silica Flour, Ground Silica, Quartz Flour, or Silicon Dioxide Powder (SiO₂) — is a premium category of industrial mineral powder produced by mining, crushing, precision-grinding, and air-classifying high-purity natural quartz rock sourced exclusively from the finest mineral belts of Rajasthan, India. The defining characteristic of Snow White grade quartz is its exceptional brightness and whiteness index (90–96+ on the Hunter Lab scale), achieved through stringent magnetic separation of iron-bearing minerals to achieve Fe₂O₃ below 0.02% — one of the lowest commercially available iron oxide levels in the world.

With a chemical formula of SiO₂ (Silicon Dioxide) and purity levels reaching 99.9% in our ultra-fine grade, Snow White Quartz Powder from Aalok Overseas India is a transformative industrial ingredient used across ceramics, glass, paints, rubber, plastics, construction chemicals, electronics, pharmaceuticals, and specialty technical applications worldwide. Its combination of maximum whiteness, ultra-high purity, precise particle size control, chemical inertness, and batch-to-batch consistency makes it the preferred choice for manufacturers across six continents.

Aalok Overseas India is a vertically integrated manufacturer operating its own mining leases, beneficiation plants, high-intensity wet magnetic separation (WHIMS) units, Raymond mills, ball mills, and dynamic air classifiers in Rajasthan's Aravalli mineral belt. Every batch is tested by XRF analysis, laser diffraction PSD measurement, Hunter Lab whiteness, pH, moisture, and oil absorption before dispatch — with a full Certificate of Analysis provided to every buyer.

Snow White Quartz Powder — Three Application-Engineered Grades

8-Step Mine-to-Micron Manufacturing Process — Snow White Grade

Achieving Snow White quality requires more processing steps than standard quartz. Our 8-stage process ensures every particle meets the highest whiteness and purity specifications.

• Selective White-Zone Mining

  Exclusive mining of naturally white, high-purity quartz veins from our Rajasthan lease areas. Only zones with visual assessment confirming bright white colour and pre-assay SiO₂ >99% are quarried for Snow White grade. Coloured or grey zones are segregated.

• Primary Crushing & Pre-Screening

  Jaw crushers reduce run-of-mine white quartz to 10–30 mm feed size. Pre-screen removes contaminated fines and dark-coloured material. Careful handling at every stage to prevent iron contamination from equipment.

• High-Pressure Washing & Attrition Scrubbing

  Removes surface clay, iron-stained coatings, and impurity films. Attrition scrubbers break open grain surface coatings to expose pristine white quartz. Critical step for final whiteness outcome without chemical treatment.

• Multi-Stage Wet High-Intensity Magnetic Separation (WHIMS)

  Two to three passes through high-gradient wet magnetic separators remove magnetite, hematite, ilmenite, and other iron-bearing minerals. This proprietary multi-pass process achieves Fe₂O₃ below 0.02% — the key to 96+ whiteness — without acid washing or bleaching chemicals.

• Drying to Specified Moisture

  Rotary dryers and fluid bed dryers reduce moisture to <0.2–0.5% depending on grade. Controlled drying temperature preserves crystal structure. Moisture is measured and verified before grinding.

• Precision Milling — Grade-Specific Circuits

  Dedicated milling circuits for each grade (ball mill for coarser, Raymond mill and impact mill for finer grades) ensure zero cross-contamination between Standard, High Purity, and Ultra-Fine grades. Mill wear-parts monitored to prevent iron contamination from milling media.

• Air Classification & PSD Control

  Dynamic air classifiers with closed-circuit separation achieve tight particle size distributions. D97 and D50 are controlled to specification. Over-size particles are returned to the mill; under-size fines are separated for micron-grade products.

• Full QC Testing, Packing & Export Documentation

  Every batch: XRF chemistry, laser diffraction PSD, Hunter Lab whiteness, moisture, pH, oil absorption, bulk density. CoA issued by accredited lab. 25 kg bags, 50 kg bags, or jumbo FIBC. Full export documentation: CoA, MSDS, invoice, packing list, phytosanitary certificate. FOB Mundra / JNPT / Chennai.
