Abstract

The present work aims an experimental design based on the of Taguchi approach to optimize the dissolution of chalcopyrite concentrate in aqueous solutions saturated with chlorine gas. The ranges of experimental parameters were between 16-45 oC for reaction temperature, 0.05-0.20 g.mL-1 for solid-to-liquid ratio, 30-120 min for reaction time, 0.027- 0.4 mol.L-1 for [Fe3+] and 0.025-0.4 mol.L-1 for [Cu2+ ]. The optimum conditions were found to be as follows: Reaction temperature (oC); 45, solid-toliquid ratio(g.mL-1); 0.05, [Fe3+](mol.L-1); 0.2, [Cu2+ ] (mol.L-1); 0,025 and reaction time(min); 120. Under these conditions, the dissolution percentage of copper from chalcopyrite concentrate in aqueous solutions saturated with chlorine was 68.44 %.
