Based on the TREO grades of the CSF, DSF, and WSF feeds, we can conclude that REE bearing minerals break relatively faster than gangue minerals during the grinding process. Consequently, a well controlled grinding process followed by a wet sieving process should produce a valuable concentrate of REE upstream from any other physical beneficiation. ## External links may be calculated when you open a workbook
