- Rare earth metals (REE) have recently encountered increasing demand for their uses in many electronics and Cleantech applications. Apatite minerals, industrially utilized for manufacturing phosphate fertilizers represent a potential secondary source of RE, as even 80 % of the RE will end up in the phosphogypsum side product.
- A low energy solution for efficient extraction of such valuable metals.
