Coconut shells are the most widely used raw material for the production of activated carbon suitable for gold production by cyanide leaching. However, increasing gold production is likely to necessitate the exploitation of other sources. Abundance and ready availability of hazelnut shells, apricot and peach stones make them a viable candidate for an alternative source. In this study, activated carbons...
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...
