Processed vein quartz for industrial applications and for further purification into higher-specification silica products.
*Estimate subject to geological documentation and mining approvals. Recoverable quantity and product characteristics vary by deposit and mining area.
Sri Lankan vein quartz can have naturally high SiO2 content.
Purity varies by deposit, vein, mining area and individual sample. Detailed geological characterisation and batch testing are essential to establish the commercially achievable product specification.
The geology of Sri Lankan vein quartz
We control the first three steps: selection, dry processing and testing. What happens after depends on your application, and we keep the two apart.
Quartz is selected at the source, leaving the host rock behind, to limit contamination before processing starts.
Dry processing: crushing, milling, screening, sorting and physical separation.
Each commercial batch is sampled and analysed. The Certificate of Analysis reports SiO2, impurity elements and particle size.
Ceramics, glass, refractories, foundry, abrasives, engineered stone, water filtration and industrial fillers.
Customers or their processors refine the material to higher specifications.
Photovoltaic, optical and semiconductor manufacturers purify and qualify their own feedstock before use.
We supply quartz grits and powder in a range of particle sizes, with chemical composition and impurity levels documented by Certificate of Analysis.
Dry-crushed and screened into controlled particle-size fractions for glass, ceramics, foundry, abrasives, engineered stone and filtration.
Milled to mesh and micron grades for ceramics, refractories, specialty glass, fillers and engineered materials.
Also refractories, foundry, abrasives, industrial fillers and construction materials, selected by particle size and the chemistry on the batch COA.
Customers who run their own purification buy our quartz as feedstock, or supply it to processors who do.
Photovoltaic, optical and semiconductor supply chains need impurity levels far below industrial grades. Our material can enter these chains only as feedstock, after additional purification and qualification by the downstream manufacturer.
A single purity figure says little about how quartz will perform. Iron tints glass. Alkalis change how a melt behaves. Particle size decides whether a grade works at all. So each batch is documented by what was measured.
Typical purity and impurity levels vary by deposit, product grade and processing route. Final specifications are confirmed by batch-specific Certificate of Analysis.
How we test| Parameter | Reported |
|---|---|
| SiO2 | Measured per batch |
| Fe2O3 | Measured per batch |
| Al2O3 | Measured per batch |
| TiO2 | Measured per batch |
| CaO, Na2O, K2O | Measured per batch |
| Other trace elements | On request, by agreed method |
| Moisture | Measured per batch |
| Particle-size distribution | Against your specification |
Volumes are quoted against the specification you need. A tight size range or chemical limit can change the tonnage we commit to.
Our processing plant is in the Embilipitiya Industrial Park, Embilipitiya 70600, Sabaragamuwa Province, Sri Lanka.
We ship FOB Hambantota or CIF to your destination port. The minimum order is one 20-foot container.

SiO2 content varies with the source material, deposit, product grade and processing route. We do not represent all products as having one fixed purity level. Each commercial batch comes with a Certificate of Analysis showing the measured SiO2 content and relevant impurity levels.
No. Our standard processed quartz is industrial quartz feedstock, not finished semiconductor-grade or photovoltaic-grade material. Applications that need exceptionally low elemental impurities may require additional downstream purification and qualification by the end user.
Our material can be supplied as feedstock for further purification. The final purity you can reach depends on the starting material, its impurity profile and the downstream purification process.
Depending on grade and particle size: ceramics, glass, refractories, foundry, abrasives, engineered materials, filtration and other industrial applications. We also supply material to customers who purify it further.
What 3N, 4N and 5N mean, why SiO2 is often calculated by difference, and what to check instead.
Why Sri Lankan vein quartz can be high in SiO2, why purity varies across a deposit, and what that means for buyers.
The stages between a quartz vein and a semiconductor fab, who runs each one, and where processed vein quartz fits.
