reactions were observed at different p H levels. At the higher p H level(p H > ~5), H2 CO3 reduction was the dominant cathodic reaction. The reaction was under activation control. At the lower pH level(pH < ~3.5), H+ reduction became the dominant one and the reaction was under diffusion control. In the intermediate area, there was a transition region leading from one cathodic reaction......

activation energy is 43.26 kJ/mol. During this process, the chemical reaction is the control step, and the reaction order of H2SO4 is 0.433 84. The third stage is the leaching of copper oxide wrapped by hematite-limonite and silicate ore with apparent activation energy of 16.08 kJ/mol, which belongs to the mixed control. Key words: copper oxide ore; H2SO4; leaching; kinetics; activation energy......
