In this paper, firstly, the in situ leaching process of ionic rare earths and the mechanism of transforming effect of in situ leaching on the material composition and structure of the soil body of the slope were studied. Then, using ammonium sulfate as a leaching agent, the distribution law of rare piles of earth in minerals, water-leaching filtrate and acid-leaching filtrate in different leaching columns was analyzed, and the equilibrium relationship of each main substance in the process of elemental migration was calculated. At the same time, based on Darcy’s law to study the change rule of the permeability and strength parameters of rare earth ore bodies in the process of leaching liquid leaching. Finally, based on the results of the study, a program for managing slopes for ionic rare earth ore is proposed. It is analyzed that the total amount of ionic rare earths in the minerals and the total amount of rare earths in the water-leaching filtrate and acid-leaching filtrate after five stages of leaching are 5.5 g, 3.25 g and 5.39 g. When the leaching solution is water, 2% ammonium sulfate and 5% ammonium sulfate, the permeability coefficients of the ore body are increased to 4.12×10−3, 5.02×10−3 and 6.56×10−3, respectively.
