Chemistry
SiO2 and buyer-specific limits for Fe2O3, Al2O3, TiO2 and other colour-forming impurities.
Silica application consulting
Glass-grade silica sand consulting
Glass production needs a stable mineral input, not an occasional good test result. Advisory work connects resource variability, impurity removal, particle-size control and plant discipline to the glassmaker's specification.

Specification lens
What must be controlled
The target is not simply “high silica.” The useful specification is the combination of mineral, process and end-use behaviour that the customer actually needs.
Particle sizing
Controlled top size, fines and distribution for batch melting, handling and segregation behaviour.
Consistency
Mine-face variation, lot control, moisture and contamination managed across sustained supply.
Process yield
Quality improvement balanced against recovery, water, drying load and operating cost.
Process architecture
Indicative equipment train
The equipment sequence is indicative. Final selection must follow representative sampling, mineralogical work and beneficiation trials.
- 01
Feed preparation
Grizzly or scalping screen, controlled feed hopper, log washer where required
- 02
Liberation
Attrition scrubber selected from clay load and surface-coating testwork
- 03
Classification
Hydrocyclones, hydraulic classifier or sizing screens with defined cut points
- 04
Impurity reduction
Magnetic separation or other separation stages only where mineralogy supports them
- 05
Finishing
Dewatering screen, dryer, final screen, controlled silos and clean dispatch system
Consulting approach
A decision path for glass-grade silica sand
Mine-to-plant technical guidance for consistent glass-grade silica sand, from deposit evaluation and beneficiation to quality control and supply planning.
Technical cautionThe equipment sequence is indicative. Final selection must follow representative sampling, mineralogical work and beneficiation trials.
- 01
Lock the customer specification
Translate the glassmaker's chemistry, size, moisture and supply limits into measurable plant controls.
- 02
Map deposit variability
Sample across mining faces and horizons so the flowsheet is not designed around one favourable sample.
- 03
Build and test the mass balance
Compare process options using recovery, impurity deportment, circulating load and water demand.
- 04
Commission the quality window
Establish operating settings, sampling frequency, stockpile rules and release criteria.
Intended outcome
A practical operating route to repeatable glass-grade product quality at commercial scale.
