| Abstract: |
| The ion-adsorption type rare earth mining has gone through pool leaching, heap leaching and in-situ leaching, and in-situ leaching method is used at present. To predict and adjust the process of solute migration in the in-situ leaching is an important content of the scientific and accurate ion-adsorption type rare earth mining. The geometric models of soil solute transport are summarized, such as the piston flow model, single capillary model and capillary bundle model. The mathematical models of soil solute transport are summed up, including the convection dispersion equation (CDE) and two-region model (MIM), stochastic model and transfer function model (TFM). The characteristics of various models and the applicability of the ion-adsorption rare earth solute transport are analyzed. The feasibility of analyzing the ion-adsorption rare earth solute transport by the theoretical model of the chromatographic tray, the geographic information system and the artificial neural network are discussed. It provides guidance for further revealing the law of solute transport in the process of in-situ leaching mine, and helps to improve the theory system of ion-adsorption type rare earth mining. Finally, the possible development trends for ion-adsorption type rare earth are suggested, which indicate the direction of future simulation study. |
