Lead Leaching with Citrate from a Galena Mineral, pH Effect

The recovery of metals from minerals through alternative processes is appropriate for the reduction of pollutants produced in foundries and traditional operations; the leaching of metals with the use of chemical reagents at low concentrations allows the reuse of the solutions, as well as the reducti...

Pantaleón Tolentino, David Moisés Calla Choque, Dandy Santos Jallath, José Enrique Lead Leaching Citrate Alkaline Plomo lixiviación Citrato Alcalino The recovery of metals from minerals through alternative processes is appropriate for the reduction of pollutants produced in foundries and traditional operations; the leaching of metals with the use of chemical reagents at low concentrations allows the reuse of the solutions, as well as the reduction of problems in the recycling of the solutions. Leaching with organic reagents at room temperature reduces the issues in the generation of gases and consumption of reagents, which is why it turns out to be an option for obtaining metals from minerals.

La recuperación de metales a partir de minerales mediante procesos alternativos es apropiada para la reducción de contaminantes producidos en fundiciones y operaciones tradicionales; la lixiviación de metales con el uso de reactivos químicos a bajas concentraciones permite la reutilización de las soluciones, así como la reducción de problemas en el reciclaje de las soluciones. La lixiviación con reactivos orgánicos a temperatura ambiente reduce los problemas de generación de gases y consumo de reactivos, por lo que resulta ser una opción para la obtención de metales a partir de minerales. Este trabajo presenta una alternativa para la recuperación de plomo mediante la lixiviación de un mineral de galena utilizando citrato de sodio en una concentración de 0.2 M a temperatura ambiente. Se evalúa el efecto del pH en medio ácido, neutro y alcalino, donde se logra recuperar el 99.9% de plomo en medio alcalino.
