    Based on the experimental evidence, it was concluded that the presence of pyrite in the leaching of chalcopyrite in H2SO4-NaCl-O2 solutions enhances the dissolution of copper through a galvanic interaction between pyrite and chalcopyrite. Additions of ferrous sulfate also increase chalcopyrite leaching rate effectively.
