| Abstract Scope |
Iron (Fe), being such an abundant element, is used in various industries such as the steel industry. Similarly, arsenic (As) can be treated to obtain an industrially useful by-product. For this reason, the leaching of arsenopyrite (FeAsS) from mining tailings is silvered, using the Thiourea (CH4 N2S)-Oxalate (C2O42-) system.
The presence of FeAsS was confirmed by XRD and SEM-EDS, while the ICP analysis indicated a content of 5.47% Fe and 0.93% As. Likewise, the parameters analyzed were [CH4 N2S] and [C2O42-]. As a result, the highest recovery of Fe was 21.29% and As of 24.04%, in concentrations of thiourea of 0.03 mol and oxalate of 0.1 mol, at 60 minutes. |
