dc.description.abstract | The effect of acetic acid and ethanol as polar aqueous solvents on sulfuric acid with hydrogen peroxide as an oxidant was studied. A small amount of these polar aqueous solvents significantly improved the copper leaching recovery. The leaching parameters such as temperature, stirring speed, H2O2 concentration, solid/liquid ratio, H2SO4concentration and particle size were examined. About 76.33% as highest Cu extraction was gained with 2 M H2O2, 600 rpm stirring speed, 50 degrees C temperature, 1 M H2SO4, 240 min of the reaction and 75 x 53 mu m particle size fraction. Further experimental tests were carried out when the stirring speed, solid-to-liquid ratio (S/L), particle size, H2O2concentration, temperature and H2SO4concentration were kept constant to investigate the effect of ethanol and acetic acid concentration in the range of 0-2 M. The experimental results proved that the copper extraction recovery reached to 99.03% in 180 min of the reaction with 2 M acetic acid. While 2 M of ethanol increased copper extraction recovery up to 100% in 90 min of the leaching time. The dissolution reaction found to be described by mixed kinetic model and activation energy of 54.37 kJ/mol. Addition of acetic acid and ethanol suggested reaction controlled by diffusion across product layer. | en_US |
