Water is needed at mine sites for dust suppression, mineral processing, coal washing, and
hydrometallurgical extraction. For these applications, water is mined from surface water …

Metal mining activities have been major contributors of potentially toxic elements (PTEs) in
the environment, leading to substantial soil pollution. One such example is lead–zinc mining …

Mining is widely regarded as having adverse effects on environment of both magnitude and
diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and …

Tailings ponds are a main heavy metal pollution source in mining areas. In this study, the
geo-accumulation index (I geo) and the potential ecological risk index (RI) are used to …

Weathering of sulphide minerals produces a large variety of Fe-oxide-bearing ochreous,
varicoloured precipitates and efflorescences of variably soluble sulphate salts. These …

Metal contamination constitutes a major source of pollution globally. Many recent studies
emphasized the need to develop cheap and green technologies for the remediation or …

Sulfide minerals are common minor constituents of the Earth's crust. In some geological
environments, sulfides constitute a major proportion of rocks. In particular, metallic ore …

Copper is one of the most dangerous soil contaminants. Soils affected by high copper
concentrations show low biodiversity and, above all, inadequate environmental quality …

The mineralogical and chemical evolution of ochreous precipitates forming from acid mine
drainage (AMD) from the abandoned Libiola Fe–Cu-sulfide mine (Eastern Liguria, Italy) was …

Heavy metal migration was evaluated in Pb–Zn tailings covered by different topsoil
constructions. The four topsoil constructions each had different interlayers: one with direct …
