observed in all pH regimes. The results from the XRD, SEM-EDS, and optical microscopic (OM) analyses of the residues indicated that the dissolution proceeded through the formation of transient phases. Cu3.39Fe0.61S4 and Cu2S were the intermediate phases at pH 0.5 and 1.0, respectively, whereas Cu5FeS4 was the major mineral at pH 1.5 and 1.8. The thermodynamic modelling predicted the sequential......
