Soilless revegetation: An efficient means of improving physicochemical properties and reshaping microbial communities of high-salty gold mine tailings

Ecotoxicology and Environmental Safety, 2021
Soilless revegetation is a cost-effective and eco-friendly method for the ecological restoration of gold mine tailings. However, due to gold mine tailings are high-salty, alkaline and low-nutrient, little research has been done on soilless revegetation ...

Water flow through tailings dams [PDF]

, 1993
Water levels in tailings dams are generally lower than those of standard earth dams. Previously, other authors have shown that embankment geometry and variation in permeability can be responsible for a concave upwards steady state seepage line.
