Copper interaction during the dissolution of gold

Therefore, in this study, a selective cyanide leaching process of gold over copper from copper-gold concentrate (also see Oraby and Eksteen, 2014) containing 490 g/t Au and 0.97% Cu present as metallic copper, oxides and sulfides has been investigated. To decrease the cyanide consumption, cyanide is added into the leach solutions to maintain a ...
