Aug 02, 2016· Eudialytes are a nonconventional source for rare earth elements (REE) As the total REE content of eudialytes is relatively low, high-grade mineral concentrates have to be produced The applicability of magnetic separation and direct selective flotation for the processing of eudialyte ore from Norra Kärr (Sweden) was tested The eudialyte in the used sample contains around 4 % of REE
titanium oxide were removed from the ore using anionic collectors The anionic collectors were added into the cell stage-wise A self-aerated sub-A Denver flotation machine (2 dm3) was used The multi-stage flotation test conditions and procedure are presented in Table 2 All the flotation products were
