Abstract

La presente invención se refiere a un proceso de extracción electrolítica de cobre adecuado para la producción de cátodos de calidad potenciada a partir de electrolitos altamente contaminados. El proceso se realiza en celdas de extracción electrolítica que incluyen una pluralidad de ánodos y cátodos, equipadas con elementos de burbujeo de gas en su parte inferior. Este comprende la etapa de burbujear gas a través de los cátodos y se caracteriza por que la solución contiene más de 100 mg/l de arsénico. La invención proporciona una solución alternativa al problema de la calidad del cátodo cuando se trata de electrolitos altamente contaminados, en particular, cuando contienen altas concentraciones de arsénico.
