- Overview
Comprehensive REE Recovery Solutions
The future depends on critical minerals and rare-earth elements (REEs) are at the heart of it. From renewable energy to electric vehicles, data centres to defence technologies, REEs form the building blocks of a digitised, electrified, and decarbonised global economy.
Yet their recovery remains one of the most complex metallurgical challenges in mining today. ENPROTEC stands at the forefront of this challenge, not merely applying existing technology, but engineering purpose-built, future-focused solutions that unlock the value of complex rare-earth deposits.
Our capabilities include laboratory testing, pilot plant campaigns and fully integrated, commercial-scale solutions. ENPROTEC delivers a complete REE recovery pathway tailored to each unique orebody.
- WE DON'T RETROFIT
We redefine.
With over two decades of experience in mineral processing innovation, ENPROTEC designs flowsheets and facilities that are scalable, effective, and tailored to the most demanding REE deposits.
| Mineral / Source | REE Group | Typical Target Uses | Beneficiation Route | Technical Considerations | Final Processing |
|---|---|---|---|---|---|
| Bastnäsite |    
|
NdFeB magnets, polishing powders, catalysts | Direct flotation with fatty acid collectors or hydroxamic acids | Slimes control critical; Ca/Fe gangue depression; surface oxidation reduces floatability; preconditioning needed | Acid bake → Leach →Solvent Extraction → Rare-earth Oxide precipitation |
| Monazite | |
Nuclear (Th), ceramics, magnets, catalysts | Flotation using hydroxamic acids or fatty acids; strong mineral locking | Radioactivity (Th) complicates handling; collector selectivity critical vs silicates; coarse liberation size (~100–150 μm) | Acid/alkali digestion → Leach → Thorium removal → Solvent Extractionn |
| Xenotime |     |
High-temp magnets, phosphors, lasers | Flotation using fatty acids, phosphoric acids, and hydroxamic acids; often mixed with monazite | Requires fine grind; separation from zircon challenging; Th-bearing; pH control for selectivity | Acid digestion → Leach → Solvent Extraction Separation → Rare-earth Oxide |
| Ion-adsorption Clays | |
Fluorescents, batteries, lasers, magnet additives | No flotation; direct in-situ leaching with ammonium sulfate or chloride | Environmentally sensitive; minimal radioactivity; low-grade; recovery efficiency depends on pH control and clay permeability | Ion-exchange or Solvent Extraction from leachate → Precipitation → Calcination |
| Mixed Carbonatites | |
Nd, Pr magnets, catalysts, glass polishing | Complex flotation circuits; multiple collectors (fatty acids, hydroxamates); multiple stages | Liberation from carbonates and iron oxides difficult; high slimes formation; reagent synergy (depressants, dispersants) essential | Acid bake → Leach → Solvent Extraction → Rare-earth Oxide or chloride |

Ore-to-Oxide Strategy Development
Precision Beneficiation & Upgrade
Effective Water Recovery & Tailings Stewardship
Modular Design & Future-flex Operations
Ore-to-Oxide Strategy Development
Fast-track your resource from exploration to production. ENPROTEC offers end-to-end metallurgical strategy design, from mineralogical characterisation and bench-scale test work to pilot studies and commercial flowsheet development. We enable our clients to de-risk early-stage decisions and progress with confidence.
Our in-house laboratory and pilot-scale facilities form the backbone of our REE design methodology, translating mineral knowledge into commercial performance.
Precision Beneficiation & Upgrade
Rare-earth recovery demands selectivity. ENPROTEC engineers customised beneficiation circuits that maximise mineral liberation and reduce impurities. Whether through flotation, magnetic separation, or our proprietary Dual Circuit Cell™ technology, our circuits are tailored to enhance concentrate grade while minimising energy and reagent inputs.
We don’t just recover minerals, we elevate them into market-ready feedstock for downstream separation and refining.
Effective Water Recovery & Tailings Stewardship
Water recovery isn’t a side benefit, it’s a necessity. ENPROTEC’s advanced dewatering technologies (including high-capacity filter presses and modular mobile units) reduce concentrate moisture, reclaim process water, and enable dry tailings management. Designed for high throughput and harsh environments, our solutions reduce freshwater dependency and environmental risk.
With ENPROTEC, water becomes a closed loop, not a lost resource.
Modular Design & Future-flex Operations
ENPROTEC’s modular design philosophy ensures that rare-earth processing facilities can scale, adapt, and relocate from pilot to production, permanent to mobile.
Our plants evolve with your ore, your strategy, and the market.

Beneficiation Upgrading
ENPROTEC applies advanced processing techniques and technologies to efficiently recover valuable minerals and enhance REE concentrate grades. Our customised approach is informed by laboratory test work and tailored to each orebody’s unique mineralogical characteristics. Resulting in a high-grade concentrate that enhances downstream processing efficiency and reduces REE losses, energy consumption, and the overall environmental impact.
Dewatering & Water Recovery
ENPROTEC offers advanced filtration technologies, including high-capacity filter presses and mobile units, to efficiently recover water and produce a dry filter cake product. This decreases concentrate moisture content, enhances water reuse, and minimises environmental risk and impact. Our solutions are designed for both large-scale permanent and mobile operations, focusing on reducing freshwater top-up requirements and enhancing operational performance throughout the REE beneficiation circuit.
