This study shows the characterization of tailings from the mining district of Coscotitlan, State of Hidalgo, Mexico. Chemical analysis by Spectroscopy of atomic absorption (AAS) allowed to quantify the concentration of Fe, Mn, Zn, and Pb as the most abundant elements in the mineral sample; in addition to the presence of Sn, Te, Bi, Ni, Co, and Cd. The presence of precious metals as the Ag (64 g ton <SUP>-1</SUP>) and Au (0.65 g ton <SUP>-1</SUP>) were identified. The greater distribution of Ag was detected in particles with diameter of 53 micron. Species as pyrite (FeS<SUB>2</SUB>), galena (PbS) and hematite (Fe<SUB>2</SUB>O<SUB>3</SUB>) were observed in a matrix of quartz (SiO<SUB>2</SUB>) by Polarized Optical Microscopy (POM), these species were also identified by X-Ray Diffraction (XRD). Both the elemental and mineralogical composition of tailings was corroborated by the technique Scanning Electron Microscopy - Energy Dispersive Microanalysis (SEM-EDS).
