Evidence of rare earth elements origin in acid mine drainage from the Iberian Pyrite Belt (SW Spain)
León, Rafael; Macías Suárez, Francisco
; Ruiz Cánovas, Carlos; Millán Becerro, Ricardo; Pérez López, Rafael; Ayora, Carlos; Nieto Liñán, José Miguel (Elsevier, 2023-02)
Acid mine drainage (AMD) is a worldwide pollution problem of watersheds. In addition to toxic metal(oid)s and acidity, many elements of economic interest are released into the environment, which make AMD a potential strategic ... -
Effects of estuarine water mixing on the mobility of trace elements in acid mine drainage leachates
Pérez López, Rafael; Millán Becerro, Ricardo; Basallote Sánchez, María Dolores; Carrero Romero, Sergio; Parviainen, Annika; Freydier, Rémi; Macías Suárez, Francisco; Ruiz Cánovas, Carlos (Elsevier, 2023)
This research reports the effects of pH increase on contaminant mobility in acid mine drainage from the Iberian Pyrite Belt by seawater mixing in the laboratory, simulating the processes occurring in the Estuary of Huelva ... -
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 ... -
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 ... -
Effects of aluminum incorporation on the schwertmannite structure and surface properties
Carrero Romero, Sergio; Fernández Martínez, Alejandro; Pérez López, Rafael; Cama, J.; Dejoie, Catherine; Nieto Liñán, José Miguel (Royal Society of Chemistry, 2022-06-15)
Schwertmannite is a common nanomineral in acid sulfate environments such as Acid Mine Drainage (AMD) and Acid Sulfate Soils (ASS). Its high surface area and positively charged surface result in a strong affinity towards ... -
Environmental management and potential valorization of wastes generated in passive treatments of fertilizer industry effluents
Millán Becerro, Ricardo; Macías Suárez, Francisco; Ruiz Cánovas, Carlos; Pérez López, Rafael; Fuentes López, José María (Elsevier, 2022-05)
A phosphogypsum stack located in SW Spain releases highly acidic and contaminated leachates to the surrounding estuarine environment. Column experiments, based on a mixture of an alkaline reagent (i.e., MgO or Ca(OH)2) ... -
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 ... -
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 ... -
Geochemical behaviour and transport of technology critical metals (TCMs) by the Tinto River (SW Spain) to the Atlantic Ocean
Ruiz Cánovas, Carlos; Basallote Sánchez, María Dolores; Macías Suárez, Francisco; Olías Álvarez, Manuel; Pérez López, Rafael; Ayora, Carlos; Nieto Liñán, José Miguel (Elsevier, 2021-04)
This paper addresses the behaviour of several technology critical metals (TCMs), i.e., rare earth elements (REEs), Y, Sc, Ga and Tl, in the Tinto River (SW Spain), quantifying their fluxes to the Atlantic Ocean and unravelling ...
