Abstract: After Cu-Ni ore powder pre-soaked in AlCl3 solution.the leaching ratios of copper and nickel can increase obviously.By X-ray diffraction analyses,electron energy spectrum analyses and electrochemical experiments,it is affirmed that,the activation of aluminum ion includes two aspects:one is the surface change of the ore by the absorption of hydrolysates,and the oth- er is the change of semiconductor characteristics of the metal sulfides by impurity aluminum ion entering the lattice,so that leaching reactions are accelerated.
