Copper and Cyanide Recovery in Cyanidation Effluents

open access: yesAdvances in Chemical Engineering and Science, 2011
Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as
