dc.description.abstractThe mineralogical changes and reaction mechanisms occurring in the Impala Platinum acid-oxygen pressure leaching process of Ni-Cu matte were postulated. The complex interactions of the various minerals with one another were clarified by considering the change in the mineral species during the leaching process. It was found that the key to the selective leaching of the nickel from the Ni-Cu matte is that while leaching Ni3S2, copper ions in solution are continuously precipitated as Cu2S in a substitution reaction liberating nickel ions into solution.
