| Abstract: |
| In ion-adsorbed rare earth mining area in southern China, earthwork removed from some construction projects under construction or planned to be constructed contains a large number of rare earth resources, which need to be recovered in time. Heap leaching processes adopted to recover stripped rare earth resources mainly include steps of yard construction, hydrometallurgical workshop construction and process operation, etc. Plant practice proves that salvage recovery heap leaching process of rare earth achieves good economic benefits and recovers valuable national strategic resources. |
