Reuse method for deposits of polymetallic tailings in a state of abandonment through the application of mineral flotation
(Springer Science and Business Media Deutschland GmbH, 2019-01-01)
In the mining industry, due to the extraction and processing of ore, a significant amount of tailings are produced which are discharged into deposits. In some cases, these are in contact with effluents and generate acid ...
Co-occurrence interaction networks of extremophile species living in a copper mining tailing
(Frontiers Media, 2022)
Copper mining tailings are characterized by high concentrations of heavy metals and an acidic pH, conditions that require an extreme adaptation for any organism. Currently, several bacterial species have been isolated and ...
Geoenvironmental characterization of the san quintín mine tailings, ciudad real (spain)
(Universidad Nacional de Colombia Sede Medellín, 2010)
The abandoned San Quintín mining group (Ciudad Real) was operated by the Sociedad Minero-Metalúrgica de Peñarroya, and 515.300 tons of galena concentrates were obtained between 1888 and 1923. Two geophysical surveys, using ...
Environmental study of gold mining tailings in the Ponce Enriquez mining area (Ecuador)
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
As a result of the artisanal mining activities in Ecuador (specially in Ponce Enriquez mining area, province of Azuay), great quantities of mining wastes have been disposed, usually without adequate management standards. ...
Characterization and treatment of artisanal gold mine tailings
(2008)
The solid waste generated by artisanal gold mining, with high mercury and gold contents, can be found in several areas in the South America. The present study focused on the tailings of an artisanal gold mine area located ...
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 ...
