Metal(loid) release from sulfide-rich wastes to the environment: The case of the Iberian Pyrite Belt (SW Spain)
Ruiz Cánovas, Carlos; Macías Suárez, Francisco; Basallote Sánchez, María Dolores; Olías Álvarez, Manuel; Nieto Liñán, José Miguel; Pérez López, Rafael (Elsevier, 2021)
Sulfide-mining wastes may lead to severe environmental and human health risks, especially challenging in abandoned mines without environmental regulation. This work is aimed at discussing the environmental problems associated ... -
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 ... -
Modelización hidrológica de las cuencas de los ríos Múrtigas y Caliente (Huelva, España). Calidad de los datos de aforos
Hydrological modeling of the Odiel River by means of th SWAT program (Soil and Water Assessment Tool) revealed a need for stream-gauge stations in the northern part ofthe basin. This is because materials with different ... -
Modelización hidrológica del río Odiel : aplicación al estudio de la contaminación por drenaje ácido de minas
Galván González, Laura (2011)
La cuenca del río Odiel está intensamente contaminada por el drenaje ácido de minas procedente de las numerosas instalaciones mineras diseminadas por toda la cuenca. Para evaluar la carga contaminante transportada por ... -
Natural and anthropic pollution episodes during the Late Holocene evolution of the Tinto River estuary (SW Spain)
Arroyo, Marta; Ruiz Muñoz, Francisco; González-Regalado Montero, María Luz; Rodríguez Vidal, Joaquín; Cáceres Puro, Luis Miguel; Olías Álvarez, Manuel; Campos Carrasco, Juan Manuel; Fernández Sutilo, Lucía; Abad de los Santos, Manuel; Izquierdo, Tatiana; Gómez Gutiérrez, Paula; Toscano Grande, Antonio; Romero Aguilar, Verónica; Gómez Álvarez, Gabriel (Consejo Superior de Investigaciones Científicas (CSIC), 2021-06)
This paper investigates the paleoenvironmental evolution of a core extracted in the middle sector of the Tinto River estuary, SW Spain, one of the most polluted areas in the world due to mining over thousands of years (>4 ... -
Pollutant transport processes in the Odiel River (SW Spain) during rain events
Ruiz Cánovas, Carlos; Olías Álvarez, Manuel; Miguel Sarmiento, Aguasanta; Nieto Liñán, José Miguel; Galván González, Laura (American Geophysical Union, 2012)
An understanding of pollutant processes in rivers under different hydrological conditions is essential to assess its long-term evolution. This is especially relevant in Mediterranean rivers during rain events, when most ... -

Seasonal evolution of natural radionuclides in two rivers affected by acid mine drainage and phosphogypsum pollution
Guerrero Márquez, José Luis; Gutiérrez Álvarez, Isidoro; Hierro Gutiérrez, Almudena; Pérez Moreno, Silvia María; Olías Álvarez, Manuel; Bolívar Raya, Juan Pedro (Elsevier, 2021-02)
The Odiel and Tinto rivers show singular characteristics due to the significant acid mine drainage (AMD) generated in the first section of their basins and the phosphogypsum (PG) stacks located on their common estuary. AMD ... -
Sobre la calidad del agua del futuro embalse de Alcolea (Cuenca del río Odiel, Huelva)
Olías Álvarez, Manuel; Nieto Liñán, José Miguel; Galván González, Laura; Miguel Sarmiento, Aguasanta; Ruiz Cánovas, Carlos (2007)
The Odiel River drains the central part of the Iberian Pyrite Belt, an area with many polymetallic massive sulphide mines that have been worked since prehistoric times. As a consequence of the oxidative dissolution of ... -
Sobre la utilización de la clasificación de las aguas de riego del U.S. Laboratory Salinity (USLS)
Olías Álvarez, Manuel; Cerón García, Juan Carlos; Fernández, I. (Sociedad Geológica de España, 2004)
One of most used methods in our country to determinate the soil salinisation and sodification risk from the irrigation water composition is the U.S. Salinity Laboratory (USLS) classification, which used the electrical ... -
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 ... -
