Abstract
The use of glycine (C2H5NO2) in the presence of thiourea (CH4N2S) for the leaching of base metals is under-researched. The aim of the study is to evaluate the influence of glycine concentration on the leaching of copper (Cu), zinc (Zn), and lead (Pb) contained in mining tailings in the presence of thiourea. The sample was previously mineralogically characterized by XRD and to know the elemental content of Cu, Zn, and Pb, the FRX and ICP techniques were implemented. For the leaching tests, different concentrations of [C2H5NO2] were used, maintaining a constant concentration of 0.1 mol l−1 of [CH4N2S], later the residual solids were characterized by XRD. As a result, a leaching of 33.02, 87.44, and 33.48% was obtained for Cu, Zn, and Pb, respectively.
