Mineral Processing
Raw run-of-mine (ROM) materials rarely match the precise thermal, physical, and chemical requirements of modern manufacturing plants. Oversized particles create blockages, excessive fines choke combustion systems, and trace impurities like iron oxide cause discoloration in glass, sanitaryware, and technical ceramics.
Our Mineral Processing division operates processing circuits engineered to strip impurities, regulate particle size distribution (PSD), and deliver homogeneous industrial mineral inputs.
Key Deliverables & Work Streams
- Crushing, Sizing & Screening: Primary jaw crushing, secondary cone reduction, and tertiary tertiary impact shaping to yield precise aggregate fractions with minimal flakiness.
- Wet Beneficiation & Desliming: High-shear log-washing, attrition scrubbing, and hydrocyclone batteries that eliminate free silica, organic matter, and ultra-fine clay slimes below 20 microns.
- Ultra-Fine Micronisation: Continuous dry and wet ball-milling integrated with dynamic rotary air classifiers to process minerals such as calcite, talc, pyrophyllite, and kaolin into powders ranging from 200 mesh down to sub-micron particle sizes.
- Engineered Aggregate (M-Sand) Production: Beneficiation plants converting hard-rock quarry spalls and basalt overburden into high-grade concrete and plaster sands compliant with IS 383 Zone II grading envelopes.
Frequently Asked Questions
What granulometric sizing and particle size capabilities are achievable?
Sizing capabilities range from coarse aggregate fractions (10 mm to 80 mm) down to continuous ball-mill ultra-fine powders (d98 < 45 µm / 200 to 500 mesh).
How does wet beneficiation remove silica and organic contamination?
High-shear log-washing, attrition scrubbing, and hydrocyclone batteries strip organic matter, free silica, and clay slimes below 20 microns.
Does your Manufactured Sand (M-Sand) comply with structural concrete standards?
Yes, M-Sand production is processed via VSI impactors and wet beneficiation plants to meet IS 383 Zone II grading envelope standards for high-strength concrete and plastering.
What chemical purity thresholds can be maintained for specialised applications?
Iron oxide (Fe2O3) levels can be controlled below 0.025% in processed silica sand and below 0.65% in kaolin clays to meet thermal, kiln, and ceramic furnace standards.
How can a client request or commission a custom test batch?
Clients can submit required chemical and particle size specification sheets to commission pilot run batches and receive verified laboratory analysis prior to full-scale production.
