A systematic voltammetric study developed in this work allows the determination of the potential range at which the selective deposition of gold and silver is carried out in the presence of a high content of copper. As a first approach, laboratory solutions prepared with a high content of cyanide and copper and low values of gold and silver are used; later, the methodology is applied to leaching solutions of industrial origin.
