Chalcocite is the second most abundant copper sulfide mineral on the earth. Chloride leaching of copper sulfide minerals, specifically chalcocite, has recently attracted interest. The dissolution of a pure chalcocite mineral in the acidic ferric chloride solution has been explored in this study. The pH and ORP values were kept constant during the leaching experiments. The effect of key parameters including ferric concentration, chloride concentration, and temperature were investigated. The shrinking core models were applied on the experimental data to describe the leaching kinetics of chalcocite. Ferric concentration and chloride concentration had a considerable effect on the first stage of chalcocite leaching, while temperature was the main key parameter affecting the kinetics of the second stage.
