Best practices of Russia in extracting ree from fertilizer waste
April 29-May 4, 2018
Rare earth elements (REE) are as well classified as EU critical metals. The Finnish apatite minerals, industrially utilized for manufacturing phosphate fertilizers represent a potential secondary source of REE. In the current fertilizer manufacturing process even 80% of the REE will end up in the phosphogypsum (PG) side product, which then holds 0.15–0.5 % of REE. So far economical means of recovering REE from apatite or PG have not been found. Novel active extraction or ion exchange methods have been recently examined by UrFU.
