| description | This is an essay in the field of metallurgical engineering. The ion-type rare earth ore in Ganzhou was treated as the research object. Continuous stirring leaching and column leaching were used to study the leaching of rare earth and impurity elements in ore samples. The test results provide a reference for the green and efficient mining of ion-type rare earth mineral resources. The test results show that the rare earth leaching rate is about 80% in the continuous stirring leaching process. The TREO/Al in the secondary leaching solution increases significantly, while the TREO/Ca decreases significantly and the TREO/Mg decreases slightly. With the increase of ore depth, the pH value of leachate gradually increased, TREO/Al increased to 15.52, and TREO/Ca decreased to 0.64. The leaching rate of rare earths all reached more than 96%, but with the increase of depth, the proportion of light rare earth increased from 49.43% to 53.28%, and the proportion of heavy rare earth gradually decreased from 35.91% to 32.18%. The continuous stirring leaching and column leaching tests both show that with the increase of the depth of the ore sample, the leaching rate of rare earth does not decrease significantly, and the leaching of rare earth in low-grade ore seams is still feasible. |
