Tailings, a by-product of mineral processing, challenge environmental restoration due to poor structure, low nutrients, and ecological risks. This study employs bibliometric methods to systematically summarize the classification, detrimental effects, and restoration technologies associated with tailings, with a particular focus on the regulatory mechanisms of organic …

Furthermore, finding new, high grade, metal deposits at, or close to the Earth's surface has become more difficult through time (Calvo et al., 2016).Therefore, mineral exploration has to identify targets that may be 100 s of metres below the surface which requires the development of new technologies to identify and extract minerals and metals using sustainable …

The geochemistry of wastes associated with arsenic processing is very different to that of AMD. Waters affected by AMD tend to have high Fe concentrations, low Ca concentrations, and low pH as a result of acid generation during sulfide oxidation (generally pyrite, FeS 2; e.g., Cheng et al., 2009).In comparison, the residues and secondary mineral growths …

In mining areas, AMD formation becomes more extensive after mine closure because pumps used to keep the water table near open-pit and/or underground mines artificially low to facilitate mining activities are turned off, leading to the rise of groundwater level, which then reacts with exposed sulfide minerals on wall rocks (Soni et al., 2014).Table 1 summarizes the …
