The increasing demand for minerals pressurizing the mining authorities to extract low-grade
ore results in more mining waste and degradation of the environment. The main aim of …

Molybdenum is an essential element for life, with growing production due to a constantly
expanding variety of industrial applications. The potentially harmful effects of Mo on the …

This study aimed to estimate the impact of an abandoned copper (Cu) mine on ecosystem
environmental quality, using integrated ecological and biogeochemical analyses. Through a …

Abandoned nonferrous metal (loid) tailings sites are anthropogenic, and represent unique
and extreme ecological niches for microbial communities. Tailings contain elevated and …

The aqueous speciation and mineralogy of antimony (Sb) in waters and tailings at Beaver
Brook antimony deposit have been analyzed to understand Sb mobility during the initial …

Extraction and processing of disseminated metalliferous ores, porphyry copper in particular,
results in significant tonnages of waste and can cause severe disturbances and …

Laboratory experiments and point observations, for instance in wetlands, have shown
evidence that microbial sulfate reduction (MSR) can lower sulfate and toxic metal …

Hydrogeochemical models for the prediction of drainage quality from full-scale mine waste-
rock piles are often parameterized using data from small-scale laboratory or field …

Globally, most high-grade ores have already been exploited. Contemporary mining tends to
focus on the extraction of lower-grade ores thereby leaving large stored tailings open to the …

Sulfidic mine tailings have to be classified as one of the major source of hazardous materials
leading to water contamination. This study highlights the processes leading to sulfide …
