Rare Earth Element (REE) Identification
Rare Earth Element (REE) Identification with XRF
Rare Earth Elements (REEs) are critical raw materials for high-tech, energy, and mobility applications. Efficient identification and recovery of REE-containing materials is an essential step in urban mining, maximising value and ensuring supply security.
The XRF-line X-ray fluorescence analyser provides fast, non-destructive, and reliable online identification of rare earth elements in moving material streams. Designed for harsh industrial environments, XRF-line enables real-time analysis and sorting of REE-bearing materials on conveyor belts.
Detectable Rare Earth Elements
Depending on system configuration and application requirements, XRF-line can identify and quantify all rare earth elements, including:
- Neodymium (Nd)
- Praseodymium (Pr)
- Dysprosium (Dy)
- Cerium (Ce)
- Europium (Eu)
- Yttrium (Y)
- Terbium (Tb)
- Other Lanthanides
This capability supports both material sorting and average composition analysis for complex material streams.
Typical Applications
The XRF-line enables reliable analysis of REE-containing materials supporting a wide range of applications across the rare earth element value chain. From real-time sorting and material separation to continuous process monitoring and recycling.
Real-Time REE Sorting
- Precise identification of high- value fractions for downstream processing.
