| Abstract: | Aiming at the existing problem of low recovery rate from ion adsorption rare earth deposit in the practical engineering, the principal reasons and ways for rare earth element loss in leaching and infiltration were analyzed in aspects of blind zone for leaching, reverse adsorption and leakage of pregnant leach solution, based on in-situ leaching process and infiltration mechanism. And six technical measures were finally proposed, including strengthening mining prospection, making more analysis for the applicability of in-situ leaching process, optimizing the stope partition and mining sequence, optimizing engineering layout and technical parameters, strengthening the monitoring of groundwater and slope, replacing the leaching agent and optimizing parameters. It is concluded that above-mentioned measures can be of important significance for those ion adsorption rare earth mining enterprises to achieve the fine production, with the production under control. |
