Mine waters as a secondary source of rare earth elements worldwide: The case of the Iberian Pyrite Belt
León, Rafael; Macías Suárez, Francisco
; Ruiz Cánovas, Carlos; Pérez López, Rafael; Ayora Ibáñez, Carlos; Nieto Liñán, José Miguel; Olías Álvarez, Manuel (Elsevier, 2021-05)
Acid Mine Drainage (AMD) generates a great concern worldwide due to its severe impact to water resources during hundreds and even thousands of years after the cessation of mining activity if control measures are not ... -
Mineral reactivity in sulphide mine wastes: influence of mineralogy and grain size on metal release
Ruiz Cánovas, Carlos; González de la Aleja Pérez, Carolina; Macías Suárez, Francisco; Pérez López, Rafael; Basallote Sánchez, María Dolores; Olías Álvarez, Manuel; Nieto Liñán, José Miguel (Copernicus Publications, 2019)
The aqueous oxidation of sulphide minerals leads to the generation of acid mine drainage (AMD), one of the main causes of water pollution worldwide. Mineral reactivity is greatly enhanced as a result of extraction and ... -
Phosphogypsum weathering and implications for pollutant discharge into an estuary
Millán Becerro, Ricardo; Pérez López, Rafael; Ruiz Cánovas, Carlos; Macías Suárez, Francisco (Elsevier, 2023)
Approximately 100 million tons of phosphogypsum were stockpiled onto marsh soils of the Tinto River estuary (Huelva, SW Spain). This study focuses on the hydraulic response of the phosphogypsum stack to the different ... -
Potential release and bioaccessibility of metal/loids from mine wastes deposited in historical abandoned sulfide mines
Ruiz Cánovas, Carlos; Quispe Guzmán, Dino Lucio; Macías Suárez, Francisco; Callejón Leblic, María Belén; Arias Borrego, Ana; García Barrera, Tamara; Nieto Liñán, José Miguel (Elsevier, 2022)
This study deals with the potential release of metal/loids from sulfide mine wastes upon weathering and the health risks associated with their accidental ingestion. To address this, a complete chemical and mineralogical ... -
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 ... -
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 ... -
Thallium distribution in an estuary affected by acid mine drainage (AMD): The Ría de Huelva estuary (SW Spain)
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Freydier, Rèmi; Parviainen, Annika; Pérez López, Rafael (Elsevier, 2022)
This study investigates the behavior of Tl in the Ría de Huelva (SW Spain), one of the most metal polluted estuaries in the world. Dissolved Tl concentration displayed a general decrease across the estuary during the dry ... -
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 ... -
Tratamiento pasivo con un sustrato alcalino disperso de drenajes ácidos de mina con alta carga metálica en la cuenca del río Odiel (Faja Pirítica Ibérica, SO España)
Caraballo Monge, Manuel Antonio; Macías Suárez, Francisco; Rötting, Tobías S.; Nieto Liñán, José Miguel; Ayora Ibáñez, Carlos (2010)
Many of the passive treatment systems treating acid mine drainage (AMD) have been focused on treating AMD with low to very low metal concentration as those existing, for instance, at coal mining districts. However all these ... -
Tratamiento pasivo de aguas ácidas de mina : evaluación de la eficiencia de un sistema a escala real en Mina Esperanza (Faja Pirítica Ibérica)
Caraballo Monge, Manuel Antonio; Macías Suárez, Francisco; Nieto Liñán, José Miguel; Ayora Ibáñez, Carlos (Sociedad Española de Mineralogía, 2010)
Durante los últimos años han sido varias las experiencias de campo llevadas a cabo en la Faja Pirítica Ibérica (FPI) para implementar un sistema de tratamiento pasivo capaz de alcanzar una óptima descontaminación de ... -
Tratamiento pasivo piloto de un drenaje ácido de mina con alta carga metálica en Monte Romero (Faja Pirítica Ibérica)
Macías Suárez, Francisco; Caraballo Monge, Manuel Antonio; Nieto Liñán, José Miguel; Ayora Ibáñez, Carlos (Sociedad Española de Mineralogía, 2010)
El drenaje ácido de mina (AMD) es uno de los principales problemas medioambientales causados por la minería de sulfuros metálicos. Un claro ejemplo de esta contaminación lo encontramos en la Faja Pirítica Ibérica (FPI) ... -
Wildfire effects on the hydrogeochemistry of a river severely polluted by acid mine drainage
Romero Matos, Jonatan; Ruiz Cánovas, Carlos; Macías Suárez, Francisco; Pérez López, Rafael; León, Rafael; Millán Becerro, Ricardo; Nieto Liñán, José Miguel (Elsevier, 2023)
This study evaluates for the first time the impact of a large wildfire on the hydrogeochemistry of a deeply AMDaffected river at the beginning of the wet season. To accomplish this, a high-resolution water monitoring campaign ...
