A Review of the Commercial Uses of Sulphate Minerals from the Titanium Dioxide Pigment Industry: The Case of Huelva (Spain)
Gázquez González, Manuel Jesús
; Contreras Llanes, Manuel; Pérez Moreno, Silvia María; Guerrero Márquez, José Luis; Casas Ruiz, Melquiades; Bolívar Raya, Juan Pedro (MDPI, 2021)
This study was focused on the historical evolution of the waste management policy carried out by the Spanish industry devoted to titanium dioxide pigments manufacturing for minimising its environmental impact. This challenge ... -
Arsenic removal procedure for the electrolyte from a hydro-pyrometallurgical complex
Paz Gómez, D. C.; Pérez Moreno, Silvia María; Gázquez González, Manuel Jesús; Guerrero Márquez, José Luis; Ruiz Oria, I.; Ríos Ransanz, Guillermo; Bolívar Raya, Juan Pedro (Elsevier, 2021)
Commercial copper (Cu) is obtained by a hydro-pyrometallurgical process, where the Cu anodes obtained in the furnaces (Cu > 99.5%) are enriched up to 99.99% in “cathodes” by electrorefining at an electrolysis plant. During ... -
Behaviour of heavy metals and natural radionuclides in the mixing of phosphogypsum leachates with seawater
Guerrero Márquez, José Luis; Pérez Moreno, Silvia María; Gutiérrez Álvarez, Isidoro; Gázquez González, Manuel Jesús; Bolívar Raya, Juan Pedro (Elsevier, 2021-01)
Phosphogypsum (PG) is disposed worldwide in large stacks usually placed in coastal zones, as in the case of Huelva (SW of Spain), where around 100 Mt of PG are stored on the salt marshes of the Tinto River estuary covering ... -
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 ... -
Immobilization of Hazardous Wastes on One-Part Blast Furnace Slag-Based Geopolymers
Paz Gómez, Daniela Carolina; Silveirinha Vilarinho, Inês; Pérez Moreno, Silvia María; Carvalheiras, João; Guerrero Márquez, José Luis; Miguel Novais, Rui; Seabra, Maria Paula; Ríos Ransanz, Guillermo; Bolívar Raya, Juan Pedro; Labrincha, João António (MDPI, 2021)
: The immobilization of hazardous wastes in ordinary Portland cement (OPC)-based materials has been widely studied and implemented. OPC-based materials have a high carbon footprint associated with their production and ... -
Influence of the accumulation chamber insertion depth to measure surface radon exhalation rates
Gutiérrez Álvarez, Isidoro; Guerrero Márquez, José Luis; Martín Domínguez, José Enrique; Adame Carnero, José Antonio; Bolívar Raya, Juan Pedro (Elsevier, 2020)
A common method to measure radon exhalation rates relies on the accumulation chamber technique. Usually, this approach only considers one-dimensional gas transport within the soil that neglects lateral diffusion. However, ... -
Radon transport events associated with the impact of a NORM repository in the SW of Europe
Gutiérrez Álvarez, Isidoro; Guerrero Márquez, José Luis; Martín Domínguez, José Enrique; Adame Carnero, José Antonio; Vargas, A.; Bolívar Raya, Juan Pedro (Elsevier, 2021)
Two radon measurement stations located to the north and south of a NORM (Naturally Occurring Radioactive Materials) repository of phosphogypsum (southwest of Europe) were used to monitor radon behavior during 2018. The ... -
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 ...
