The traditional method of extracting pure REEs from mined material is called the solvent-exchange method, and consists of first crushing the rock into smaller chunks and then grinding it into a fine dust. Unwanted materials (largely iron oxide minerals and carbonate minerals) are removed using various separation methods, leaving behind an ore of REEs and radioactive material, which are then separated using additional means of chemical leaching (Kidela 2011).

So whats left behind ore of REEs +radioactive material
