EXTRACTION PROCESS
Stage-by-Stage Mineral Recovery
01
STAGE 1
Pulp Extraction & Feedstock Conditioning
Objective: Convert stored rare earth into a stable, process-controlled pulp suitable for selective extraction.
- Pulp extracted via dredging from wet storage
- Mechanical homogenization
- Filtration using centrifuge or filter press
- Liquid-to-solid ratio ~5:1
Ensures process uniformity across Indian, Australian, Middle Eastern, and North American residues.
02
STAGE 2
Two-Stage Aluminum Recovery
Objective: Extract residual aluminum while enriching the solid phase in iron and critical metals.
- NaOH concentration ~4M at ~100°C
- First-Stage NaOH Leaching → Filtration
- CO₂-Assisted Precipitation (~75°C)
- Second-Stage NaOH Leaching
Extracts up to ~40% aluminum. Uses industrial exhaust CO₂ streams.
03
STAGE 3
Carbonate Leaching of Ti, Zr, Sc & REEs
Objective: Selective mobilization of strategic and high-value metals.
- Na₂CO₃ + NaHCO₃ solution (~2M) at ~70°C
- Cold plasma & electromagnetic activation
- Electric pulse action (EPA)
- CO₂ pre-saturation at atmospheric pressure
Up to ~60% Scandium, ~50% Zirconium, and ~50% REEs extracted.
04A
STAGE 4A
Fractionated Metal Recovery: Titanium
Dissolved metals are separated sequentially through controlled precipitation — not recovered as a mixed concentrate.
- Precipitation at ~75°C
- NaOH-assisted precipitation
- Coagulant addition
- Ultrasound enhancement
Output: TiO₂ concentrate suitable for pigment, alloy, and industrial use.
04B
STAGE 4B
Zirconium, Scandium & REE Recovery
Conditions: Heated to ~100°C, NaOH ~4M, pH ~14, Aluminum-based coagulant.
- Zirconium oxide (ZrO₂)
- Scandium oxide (Sc₂O₃)
- Yttrium oxide, Dysprosium & Gadolinium compounds
Suitable for aerospace ceramics, permanent magnets, defense, and energy transition technologies.
FIN
FINAL SOLID MANAGEMENT
Iron Enrichment
After sequential extraction, the solid phase is enriched to ~60% Fe, then neutralized to pH 7–9.
- Iron pigments
- Pellets & Coagulants
- Smelting feedstock
The remaining aluminosilicate matrix is mineralogically stabilized.
SUSTAINABILITY
Reagent Recovery & CO₂ Integration
The system incorporates a fully closed-loop design that significantly reduces fresh chemical input, waste generation, carbon intensity, and operating expenditure.
NaOH & Na₂CO₃ Regeneration
Reagent loops recover and reuse leaching chemicals at industrial scale.
CO₂ Capture & Reinjection
Industrial exhaust CO₂ is stored and reinjected directly into the precipitation stages.
Zero Net Waste Target
Every output stream is a saleable product — from iron pigments to aluminosilicate materials.
STRATEGIC RARE EARTHS
Targeted Critical Metals
Yttrium (Y)
Plays a critical position in high-technology manufacturing. Our fractionated recovery isolates Yttrium oxide which is heavily used in laser systems, aerospace alloys, and advanced ceramics.
