This study was carried out to define efficient operating conditions to solubilize these metals by a chemical leaching technique. The comparison of different leaching reagents (HCl, H2SO4, CH3COOH, and EDTA) has revealed that sulfuric acid leaching coupled with the addition of sodium chloride is the most interesting option for the solubilization of Cu, Pb, Sb, and Zn from the finest fractions (<125μm) of SASR soil. The initial metal contents of the soil sample were 1,760mg Cu kg−1, 43,300mg Pb kg−1, 780mg Sb kg−1, and 355mg Zn kg−1. The important operational parameters for leaching ([H2SO4], [NaCl], pulp density, reaction time, and temperature) were also studied. The optimum leaching conditions identified were 1M H2SO4 and 4M NaCl with a 10% (w/v) soil pulp density at ambient temperature. In these conditions, 83, 75, 61, and 72% of Cu, Pb, Sb, and Zn were respectively solubilized after only 1h of treatment. The use of five successive leaching steps and two washing steps removed 96, 99, 84 and 86% of Cu, Pb, Sb, and Zn respectively from the soil.
