Abstract

La presente invención se refiere a metales valiosos, y especialmente cobre y plata, que se recuperan de un electrolito que contiene plomo en un proceso en el que el electrolito se alimenta a un reactor de pulido electroquímico que tiene un cátodo de alta área superficial en el que el potencial de electrodo se controla para reducir preferentemente el cobre y plata y para formar un electrolito enriquecido con plomo pretratado que luego se puede someter a recuperación electroquímica de plomo.
