dc.description.abstract Dissolution of chalcopyrite and manganese dioxide minerals in the presence of each other in sulfuric acid medium was studied using compact disc electrodes of the minerals under various H(2)SO(4) concentrations (0.05 to 0.5 M). [H(+)] had a positive effect on the reaction rate. Strong galvanic interaction was observed to take place between chalcopyrite and manganese dioxide, the galvanic interaction predominating over the individual dissolution (self-corrosion) rates. Evans diagrams constructed from polarization curves of the two minerals were helpful in interpreting the leaching data. The electrochemical nature of the dissolution reaction was analyzed through application of the Butler-Volmer equation and was confirmed from polarization measurements conducted with the respective mineral electrodes.
