Thermodynamic study of the leaching of recycled lead with sodium citrate
Lead batteries represent 60% of the world’s electric storage batteries. Nearly 50% of lead consumption worldwide comes from recycled and reused materials. Currently, pyrometallurgical methods represent more than 90% of the technology for lead recovery; However, these processes are...

Nearly 50% of lead consumption worldwide comes from recycled and reused materials. Currently, pyrometallurgical methods represent more than 90% of the technology for lead recovery; However, these processes are criticized due to the emission of sulfur dioxide due to the decomposition of lead sulphate at elevated temperatures, in addition to the emission of particles. The recovery of lead by the recycling of batteries by hydrometallurgical processes has been investigated as an alternative to pyrometallurgical processes. In the present work, a thermodynamic analysis of lead leaching with sodium citrate was carried out. The thermodynamic analysis was based on the study of three stability diagrams constructed with Medusa® software. Leaching tests were carried out that allowed knowing the system, corroborating the thermodynamic analysis carried out and studying the behavior of the system. The results obtained show that it is possible to extract 100% lead with a concentration of leaching agent of 0.25 M, liquid solid ratio 1:1 and 25 ºC.Las baterías de plomo representan el 60% de las baterías de almacenamiento de energía eléctrica del mundo. Cerca del 50% del consumo de plomo a nivel mundial proviene de materiales reciclados y reutilizados. Actualmente, los métodos pirometalúrgicos representan más del 90% de la tecnología para recuperación de plomo; sin embargo, estos procesos son criticados debido a la emisión de dióxido de azufre por la descomposición de sulfato de plomo a temperaturas elevadas, además de las emisiones de partículas. La recuperación de plomo mediante el reciclaje de baterías por procesos hidrometalúrgicos ha sido investigada como una alternativa a los procesos pirometalúrgicos. En el presente trabajo se realizó un análisis termodinámico de la lixiviación de plomo con citrato de sodio. El análisis termodinámico se basó en el estudio de tres diagramas de estabilidad construidos con el software Medusa®. Se realizaron pruebas de lixiviación que permitieron conocer el sistema, corroborar el análisis termodinámico realizado y estudiar el comportamiento del sistema. Los resultados obtenidos muestran que es posible extraer 100% de plomo con una concentración de agente lixiviante de 0.25 M, relación sólido líquido 1:1 y 25 °C. application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/7262/7264Ciencia En Desarrollo; Vol. 9 No. 2 (2018): Vol 9, Núm. 2 (2018): Vol 9, Núm 2(2018): Julio- Diciembre; 119-126Ciencia en Desarrollo; Vol. 9 Núm. 2 (2018): Vol 9, Núm. 2 (2018): Vol 9, Núm 2(2018): Julio- Diciembre; 119-1262462-76580121-7488hidrometalurgia del plomoreciclaje de materialeslixiviación del plomoreactivos orgánicosHidrometalurgialead hydrometallurgy, material recycling, sodium citrate, thermodynamicsThermodynamic study of the leaching of recycled lead with sodium citrateEstudio termodinámico de la lixiviación de plomo reciclado con citrato de sodioinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1http://purl.org/coar/access_right/c_abf2Villa, Lina ConstanzaSaldarriaga Agudelo, WilmerRojas, Nestor Ricardo001/15237oai:repositorio.uptc.edu.co:001/152372025-07-18 10:56:46.292metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
