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 ... -
Copper Flash Smelting Process Balance Modeling
Bacedoni, María; Moreno-Ventas Bravo, Ignacio; Ríos Ransanz, Guillermo (MDPI, 2020-09)
Process control in flash smelting is based on mass and energy balance from which the operational parameters (oxygen coefficient, oxygen enrichment, and flux demand) are obtained to achieve matte and slag with defined ... -

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 ... -
Removal of Sb Impurities in Copper Electrolyte and Evaluation of As and Fe Species in an Electrorefining Plant
González de las Torres, Ana Isabel; Moats, Michael S.; Ríos Ransanz, Guillermo; Rodríguez Almansa, Ana; Sánchez-Rodas Navarro, Daniel Alejandro (MDPI, 2021-05)
Antimony and arsenic concentrations and their oxidation states (Sb(III), Sb(V), As(III) and As(V)) in copper electrorefining electrolyte can affect copper cathode quality through the formation of floating slimes. A ...
