Application of the Thiocyanate-Thiourea System for the Leaching of Copper Present in Tailings from Pachuca, Hidalgo, Mexico
摘要
In this study, an investigation is carried out applying the thiocyanate-thiourea systemThiocyanate-Thiourea System, for the extraction of copperCopper present in the tailings of the region of Pachuca, Hidalgo, Mexico. MetallurgicalMetallurgical mining wasteMining waste is known for its environmental impactEnvironmental impact, but it also contains base metalsBase metals of economic interest, such as copperCopper (Cu). Prior to the leachingLeaching processProcess, the sample was characterized by XRDX-ray diffraction (XRD), SEM-EDS, ICP-MS, and FRX techniques to determine the mineralogy present and the elemental content of Cu. The parameters analyzed were [Thiocyanate] and [Thiourea]. After a reaction time of 60 min, a maximum dissolution of 97.63% was obtained.
