| Abstract: |
| With the increasing depletion of high grade ion-absorbed rare earth resources, it is an important problem to make an inventory of the low grade ion-type rare earth resources and realize the sustainable development of mining economy. In order to solve the technical problems of low grade ion-type rare earth resource exploitation, the in-situ leaching test technology of low grade ion-type rare earth resources was studied based on the characteristics of the low grade ion-type rare earth resources and the latest in-situ leaching technology. On the basis of the industrial experiment, a set of complete technological process was developed which solved the problems of high cost and serious environmental pollution of low grade ion-type rare earth resource. It provides a reliable technical support for the promotion of the in-situ leaching process and the recovery of the low grade ion-absorbed rare earth resources. |
