Ion-adsorbed rare-earth ores are mined using in-situ leaching, and their mechanical properties significantly affect the efficient and safe recovery of rare earth elements. However, the mechanism of the change in the mechanical properties of the ore body due to the physicochemical processes caused by leaching remains unclear.

Rare earth elements (REE) are important resources, but REE in the environment are also deemed to be a new class of pollutant. Phytoremediation, using the hyperaccumulator Dicranopteris pedata, offers a promising approach for reclaiming and recycling REE from mining tailings. However, how in situ leaching affects the topsoil characteristics of mining areas and …
