Abstract Exposed mine tailings could release substantial amounts of toxic metal-rich colloidal particles into soils during drying–wetting (D–W) cycles, but the mechanisms are still incompletely understood. In this study, two-layered (tailings above and soils below) packed columns were set to explore the effects of D–W cycles on tailing …
Some coal mines have been closed and more will be closed in the future. In 2020, the number of abandoned coal mines in China reached 12,000, and it is expected to reach 15,000 by 2030 .
