Electrochemical Features of the Ferric Sulfate Leaching of CuFeS2/C Aggregates.

Abstract

The rate of chalcopyrite dissolution by ferric sulfate solution can be enhanced by the presence of conductive carbon particles. The addition of carbon has been found to increase the leaching rate of chalcopyrite by as much as a factor of four. The importance of carbon in the enhanced leaching of chalcopyrite has been discussed in previous publications. The same rate increase has been found to prevail for the initial reaction kinetics. To further evaluate the effect of carbon during the initial stage of reaction, the results from initial rate experiments are discussed in conjunction with polarization and spectroelectrochemical measurements.
