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 ... -
Caracterización y valorización de residuos inorgánicos procedentes de industrias químicas de Huelva
(Universidad de Huelva, 2018)Waste is currently one of the most serious environmental problems arising from the economic and social development of human beings, mainly because of the amount of waste continues to increase year after year. The emergence ... -
Characterization of Two Sludges from a Pyrometallurgical Copper Smelting Complex for Designing a Se and Pb Recovery Proposal
Paz Gómez, D. C.; Pérez Moreno, Silvia María; Ruiz Oria, I.; Bolívar Raya, Juan Pedro (Springer, 2020-08)
Gas scrubbing sludge (SS) and fine dust of converters (SC) are wastes generated in the off-gas cleaning system of smelting and converting processes. Both wastes are considered hazardous materials due to their high metal ... -
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 ... -
Phosphogypsum as additive 1 for foamed bitumen 2 manufacturing used in asphalt paving
Cuadri Vega, Antonio Abad; Pérez Moreno, Silvia María; Altamar, C.L.; Navarro Domínguez, Francisco Javier; Bolívar Raya, Juan Pedro (Elsevier, 2021-02)
The aim of this work was to use phosphogypsum (FY) waste in a sustainable paving practice involving the production of FY-foamed bitumen for road applications. For this proposal, three FY types coming from different fertilizer ... -
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 ...
