| Abstract: | On the basis of the study on the process mineralogy of rare earth leached residues,a combined magnetic separation-flotation process was proposed to recover rare earths from above mentioned rare earth leached residues after optimizing experimental research on technological conditions of magnetic separation and of flotation. The rare earth concentrate obtained by the process contained REO of 48.97% with recovery of 91.59%. The secondary recovering technology for rare earths from rare earth leached residues provided a effective utilization way for rare earth production enterprises. |
