Stream-pit lake interactions in an abandoned mining area affected by acid drainage
Fuentes López, José María; Olías Álvarez, Manuel
; León, Rafael; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Moreno González, Raúl; Ruiz Cánovas, Carlos (2022)
Opencast mining of sulfide ore deposits may lead to the formation of anthropogenic acidic lakes with highly polluted waters. In these systems, it is crucial to understand the hydrological connections between surface and ... -
Surface and Groundwater Quality Evolution in the Agrio and Guadiamar Rivers After the Aznalcóllar Mine Spill (SW Spain): Lessons Learned
Olías Álvarez, Manuel; Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores (Springer, 2020-09)
The failure of the tailing dam at the Aznalcóllar mine (SW Spain) in 1998 released ≈ 6 million m3 of pyrite sludge and acidic waters, and caused an enormous environmental disaster in the Agrio and Guadiamar rivers. A small ... -
Temporal evolution of acid mine drainage (AMD) leachates from the abandoned tharsis mine (Iberian Pyrite Belt, Spain)
Moreno González, Raúl; Macías Suárez, Francisco; Olías Álvarez, Manuel; Ruiz Cánovas, Carlos (Elsevier, 2021)
Acid mine drainage (AMD) due to the mining of sulfide deposits is one of the most important causes of water pollution worldwide. Remediation measures, especially in historical abandoned mines, require a deep knowledge of ... -
Temporal variations of REE in several AMD sources of the Odiel River (SW Spain)
Olías Álvarez, Manuel; Ruiz Cánovas, Carlos; Riera Bayo, Julia (Elsevier, 2017)
Waters affected by acid mine drainage (AMD) can contain high concentrations of rare earth elements (REE) which have a great interest not only by its application as tracers in hydrogeochemical processes but also as a ... -
Thallium in environmental compartments affected by acid mine drainage (AMD) from the Iberian Pyrite Belt (IPB): From rocks to the ocean
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Olías Álvarez, Manuel; Pérez López, Rafael; Nieto Liñán, José Miguel (Elsevier, 2022)
This works investigates the origin, behavior and fate of Tl in acid mine drainage (AMD) affected areas at catchment scale, following the path from rocks to the ocean. To address this issue, comprehensive data set of Tl in ... -
The Evolution of Pollutant Concentrations in a River Severely Affected by Acid Mine Drainage: Río Tinto (SW Spain)
Olías Álvarez, Manuel; Ruiz Cánovas, Carlos; Macías Suárez, Francisco; Basallote Sánchez, María Dolores; Nieto Liñán, José Miguel (MDPI, 2020-06)
The Río Tinto, located in the Iberian Pyrite Belt (SW Spain), constitutes an extreme case of pollution by acid mine drainage. Mining in the area dates back to the Copper Age, although large-scale mining of massive sulfide ... -
Variación estacional en la especiación y movilidad de Fe y As en aguas afectadas por drenajes ácidos de mina en la cuenca del río Odiel (Huelva)
Miguel Sarmiento, Aguasanta; Casiot, C.; Nieto Liñán, José Miguel; Elbaz Poulichet, F.; Olías Álvarez, Manuel (Sociedad Geológica de España, 2004)
The Odiel river drains the central part of the Iberian Pyrite Belt, one of the oldest and most important massive sulphide districts in the world. In these massive sulphide deposits, arsenic can be found in arsenical pyrite ...
