ABSTRACTThe selective chlorination of cyanidation tailing (CT) for the extraction of gold and silver has been investigated. The reaction operated at different conditions and their effect on the extraction of Au and Ag was studied. The mineral samples were characterized by fire assay, Xray diffraction (XRD), Xray fluorescence (XRF) and scanning electronic microscopy (SEM).
