Abstract
The leaching mechanisms of chalcopyrite, sphalerite, and chalcocite with hypochlorous acid have been resolved by analyzing the concentrations of the products of the leaching reactions and also by determining the effects of pH on the leaching rate. Chalcopyrite and sphalerite give rise to sulfur and sulfate as the primary products and the leaching rates are pH independent. However, chalcocite gives rise to only sulfur as the primary product, and the leaching rates are pH dependent.
