The primary solid waste product of surface coal mining is overburden (also known as spoil),
the material that is moved to access the underlying coal seams. Once removed, this material …

Permeability in reactive porous media evolves in complex ways that are hard to predict.
Macroscopic empirical equations are often used to estimate permeability evolution but fail to …

Cadmium (Cd)-bearing sphalerite and smithsonite ore particles are ubiquitous in soils near
metal-mining areas. Previous studies indicate that smithsonite is more readily dissolved in …

Historical and abandoned coal mine spoil continues to generate acid-and metal (loid)-rich
porewaters and represents a geographically large and diffuse non-point source of …

The objective of this study is to obtain a more detailed assessment of particles that contain
rare-earth elements (REEs) in abandoned deposits of Brazilian fine coal tailings (BFCTs), so …

The behavior of arsenic (As) in groundwater is closely related to the sulfidation of
ferrihydrite. In the ternary ferrihydrite-As-sulfide system, ferrihydrite can either initially adsorb …

Long-term coal mining operations have been linked to increases in HM concentrations in
subterranean soils, which degrades soil quality. The clusters of coal mines and mine tailings …

The release of colloid-bound trace metals from abandoned coal mine spoils can potentially
be a significant source of contamination during weathering. We examined the size …

Coal mine spoil is widespread in US coal mining regions, and the potential long-term
leaching of toxic metal (loid) s is a significant and underappreciated issue. This study aimed …

Anthropogenic changes to soil properties and development can dominate soil systems,
particularly in coal mining-impacted landscapes of the Appalachian region of the United …
