Geochemical processes controlling the distribution and concentration of metals in soils from a Patagonian (Argentina) salt marsh affected by mining residues
(Elsevier Science, 2017-10)
Heavy metal pollution that affects salt marshes is a major environmental concern due to its toxic nature, persistence, and potential risk to organisms and to human health. Mining waste deposits originated four decades ago, ...
Mechanism of removal and retention of heavy metals from the acid mine drainage to coastal wetland in the Patagonian marsh
(Pergamon-Elsevier Science Ltd, 2017-05)
The attenuation of the acid mine drainage is one of the most important environmental challenges facing the mining industry worldwide. Mining waste deposits from an ancient metallurgical extraction of heavy metals were found ...
Source patterns of potentially toxic elements (PTEs) and mining activity contamination level in soils of Taltal city (northern Chile)
(Springer, 2020)
Mining activities are among the main sources of potentially toxic elements (PTEs) in the environment which constitute a real concern worldwide, especially in developing countries. These activities have been carried out for ...
Characteristics of an iron-reducing, moderately acidophilic actinobacterium isolated from pyritic mine waste, and its potential role in mitigating mineral dissolution in mineral tailings deposits
(2020-07)
Reactive pyritic mine tailings can be populated by chemolithotrophic prokaryotes that enhance the solubilities of many metals, though iron-reducing heterotrophic microorganisms can inhibit the environmental risk posed by ...
Advances in Mine Tailings and Water Management in the Mining Industry for a Circular Economy
(2020)
The mining industry consumes vast quantities of water and energy to produce a metal or mineral product from mineral resources on the earth’s crust, leaving an enormous amount of mining waste. The linear thinking of the ...
Environmental geochemistry of an epigenetic Pb-Zn-Ag deposit at the abandoned Cecilia mine, Puno region, Peru
(The University of QueenslandAUS, 2022)
The abandoned Cecilia Pb-Zn-Ag mine is located at the headwaters of the Lake Titicaca watershed in the Altiplano of Peru. The site is characterized by three months of high precipitation and nine months of limited precipitation. ...

Lithium recovery from brines: A vital raw material for green energies with a potential environmental impact in its mining and processing
(Elsevier, 2018-10)
The electrification of our world is driving a strong increase in demand for lithium. Energy storage is paramount in electric and hybrid vehicles, in green but intermittent energy sources, and in smart grids in general. ...
Analysis of the potential application of geophysical survey (induced polarization and DC resistivity) to a long-term mine planning in a sulfide deposit
(2020-10-01)
Medium- and long-term mine planning depends on a large series of probes to determine the continuity and content of mineralized zones and the development direction of the exploration. In addition to being logistically complex ...
