| Abstract: | The reaction kinetics of the mixed acid (H2SO4 HNO3) leaching of compositecopper ore was studied. The influence of temperature, particle size and leaching solution concentration on extraction of copper was investigated. The results show that the leaching processfits in a surface reaction control model. The apparent activation energy was calculated to be45.73 kJ/mol. The order of the reaction was 0.5 with respect to H and 1 with respect to NO3.The kinetic equation of the reaction is given by |
