Chemical Composition Data of the Main Stages of Copper Production from Sulfide Minerals in Chile: A Review to Assist Circular Economy Studies

Santana-Barros, Kayo; Vielmo, Vicente Schaeffer; Garrido Moreno, Belén; Riveros, Gabriel; Cifuentes, Gerardo; Moura Bernardes, Andrea (MDPI AG, 2022-02)

[EN] The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are ...
Electrochemical treatment of a synthetic wastewater containing a sulphonated azo dye. Determination of naphthalenesulphonic compunds produced as main by-products

Del Río García, Ana Isabel; Fernández Sáez, Javier; Molina Puerto, Javier; Bonastre Cano, José Antonio; Cases Iborra, Francisco Javier (Elsevier, 2011-06-15)

The electrochemical treatment of wastewaters from textile industry is a promising technique for substances which are resistant to biodegradation. This paper deals with the electrochemical decolourisation/degradation of ...
Estudio de la recuperación mediante electrodeposición de antimonio y bismuto presentes en efluentes generados en la industria de obtención de cobre

Muñoz Pérez, Alejandro (Universitat Politècnica de València, 2023-10-03)

[ES] El antimonio y el bismuto son dos compuestos críticos según la UE. La disponibilidad limitada de estos ha aumentado la necesidad de explotar fuentes alternativas a su extracción directa. Además, la industria del cobre ...
Estudio electroquímico para la recuperación de antimonio de efluentes del electro-refinado de cobre por electrodeposición

Hernández Pérez, Lorena (Universitat Politècnica de València, 2024-04-27)

[ES] Esta Tesis Doctoral se centra en la recuperación mediante electrodeposición del Sb presente en un efluente residual proveniente de la metalurgia del cobre. El efluente en el que se basa este estudio se produce en el ...
Membrane electrolysis for recovering Sb and Bi from elution solutions of ion-exchange resins used in copper electrorefining: A cyclic voltammetric study

Santana-Barros, Kayo; Machado, André Luiz Vargas; Vielmo, Vicente Schaeffer; Velizarov, Svetlozar; Ferreira, Jane Zoppas; Pérez-Herranz, Valentín; Bernardes, Andrea Moura (Elsevier, 2022-11-01)

[EN] Antimony (Sb) and bismuth (Bi), which have been considered critical raw materials by the European Commission, cause inconveniences to copper production when they are present as impurities in copper elec-trorefining ...
Selective oxidation of propane over alkali-doped Mo-V-Sb-O catalysts

Ivars Barceló, Francisco; Solsona Espriu, Benjamin Eduardo; Botella Asuncion, Pablo; Soriano Rodríguez, Mª Dolores; López Nieto, José Manuel (Elsevier, 2009-03-30)

[EN] Alkali metal-doped MoVSbO catalysts have been prepared by impregnation of a MoVSbO-mixed oxide (prepared previously by a hydrothermal synthesis) and finally activated at 500 or 600 degrees C in N-2. The catalysts have ...
Study of the use of deep eutectic solvents for the recovery of antimony by electrodeposition

Gravensteyn, Cas (Universitat Politècnica de València, 2024-10-02)

[ES] La Comisión Europea emite una lista anual de sustancias que se declaran como Materias Primas Críticas. Esta lista incluye metaloides, como el antimonio, que son de especial relevancia para la industria y están en ...
Voltammetric and electrodeposition study for the recovery of antimony from effluents generated in the copper electrorefining process

Hernández-Pérez, Lorena; Carrillo-Abad, Jordi; Ortega Navarro, Emma María; Pérez-Herranz, Valentín; Montañés, Maria-Teresa; Martí Calatayud, Manuel César (Elsevier, 2022-12)

[EN] Antimony is a metalloid with limited availability as a primary resource, but it is commonly found as an impurity in effluents generated in the copper metallurgy. Thus, the development of clean and selective processes ...
