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) ... -
Evaluation of the impact produced by the Huelva phosphogypsum stacks on their estuarine environment
(Universidad de Huelva, 2021)The manufacturing of phosphoric acid from the chemical attack of the phosphate rock with sulfuric acid (wet process), generates phosphogypsum (PG) as a waste. PG is mainly composed of gypsum, but also contains high levels ... -
Hydrogeochemical and mineralogical study of the ecological treatment of phosphogypsum leachates
(Universidad de Huelva, 2022)The production of phosphoric acid in the phosphate fertilizer industry, via the wet chemical attack of phosphate rock with sulfuric acid, generates an unwanted by-product known as phosphogypsum. This waste is mainly composed ... -
Modelos de funcionamiento hidrogeoquímico de embalses afectados por AMD en base a indicadores biológicos. Interés y relevancia de las diatomeas en el caso de la Faja Pirítica Ibérica
(Universidad de Huelva, 2022)La construcción de embalses en regiones sometidas a climas áridos es una técnica habitualmente empleada para almacenar aguas para posterior uso urbano, agrícola e industrial. En el escenario que nos ocupa, suroeste de ... -
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 ... -
The La Luna/Río Negro(.) Petroleum system at the Urdaneta West Field, lake Maracaibo basin, NW Venezuela: ID basin modelling and secondary oil migration
Escobar, Marcos; Díaz, J. G.; Márquez Martínez, Gonzalo; Boente López, Carlos; Tocco, R. (Wiley, 2022)
This paper investigates the timing of hydrocarbon generation in the northern part of the Urdaneta West field in the NW of the Lake Maracaibo Basin, NW Venezuela, based on ID basin modelling at three wells referred to as ...
