A fractal model to describe the evolution of multiphase flow properties during mineral dissolution
Guarracino, Luis; Roetting, Tobias Stefan; Carrera Ramírez, Jesús (Elsevier, 2014-05-01)
Article
Accés restringit per política de l'editorialUnderstanding the changes in multiphase flow parameters caused by mineral dissolution-precipitation is required for multiple applications ranging from geological storage of CO2, enhanced geothermal energy production or ... -
Acid mine drainage in the Iberian Pyrite Belt: 2. Lessons learned from recent passive remediation experiences
Ayora Ibáñez, Carlos; Caraballo, Manuel A.; Macías Suárez, Francisco; Roetting, Tobias Stefan; Carrera Ramírez, Jesús; Nieto Liñán, José Miguel (2013-11)
Article
Accés restringit per política de l'editorialThe Iberian Pyrite Belt (IPB), SW Spain and Portugal, contains about 100 abandoned mine wastes and galleries that release acid mine drainages (AMD) to the Tinto and Odiel rivers. In situ passive remediation technologies ... -
Characterization of flow parameters and evidence of pore clogging during limestone dissolution experiments
Luquot, Linda; Roetting, Tobias Stefan; Carrera Ramírez, Jesús (2014-08-01)
Article
Accés restringit per política de l'editorialRock dissolution induces changes in texture (porosity, pore-size distribution, or tortuosity) which modify multiphase flow and transport properties (permeability, diffusion coefficient, retention curve). Limestone dissolution ... -
Environmental distribution and health impacts of As and Pb in crops and soils near Vinto smelter, Oruro, Bolivia
Roetting, Tobias Stefan; Mercado, M; Garcia, M. E.; Quintanilla, J. (2014-05-01)
Article
Accés restringit per política de l'editorialThe Vinto Sb-Sn smelter (Oruro, Bolivia) has been linked to arsenic and heavy metal pollution in air, soils, residual waters of the smelter, and hair and urine of workers, but crop concentrations had not been assessed ... -
From highly polluted Zn-rich acid mine drainage to non-metallic waters: Implementation of a multi-step alkaline passive treatment system to remediate metal pollution
Macías, Francisco; Caraballo, Manuel A.; Roetting, Tobias Stefan; Pérez López, Rafael; Nieto, José Miguel; Ayora Ibáñez, Carlos (2012-09-01)
Article
Accés restringit per política de l'editorialComplete metal removal from highly-polluted acid mine drainage was attained by the use of a pilot multistep passive remediation system. The remediation strategy employed can conceptually be subdivided into a first section ... -
Use of hydraulic tests to identify the residual CO2 saturation at a geological storage site
Martínez Landa, Lourdes; Roetting, Tobias Stefan; Carrera Ramírez, Jesús; Russian, Anna; Dentz, Marco; Cubillo, Bruno (Elsevier, 2013-11-01)
Article
Accés restringit per política de l'editorialEstimating long term capillary trapping of CO2 in aquifers remains a key challenge for CO2 storage. Zhang etal, (2011) proposed a combination of thermal, tracer, and hydraulic experiments to estimate the amount of CO2 ...
