摘    要：对风化壳淋积型稀土矿浸取过程中的浸取水动力学、原地浸出渗流规律、浸取稀土动力学、浸取铝动力学、浸取传质浸取过程选择性等基础理论现状进行了概括和分析指出了目前浸取过程中存在的一些问题和面临的挑战，特别指出应在浸铝浸取动力学过程研究、浸取过程强化研究、堆浸、原地浸出基础理论研究方面有待进一步加强。

Abstract: This paper summarizes the theoretical research developments on leaching hydrodynamics, permeability rule of in-situ leaching, leaching kinetics, leaching process selection and leaching mass transfer on the leaching process of weathered crust elution-deposited rare earth ore. Some problems and challenges existed in the present leaching process are discussed, including leaching kinetics on aluminum, leaching process intensification and fundamental research on in-situ, need to be further strengthened.
