Abstract Scope |
The study of the benefit of noble metals is of utmost importance at an industrial level, when dealing with a mining-metallurgical waste the complexity of the process increases due to factors such as the characteristic refractoriness of these wastes. As an alternative to achieve the highest silver dissolutions, a chemical granulometric analysis was performed where it was determined that 40.61% of silver contained in the tailings sample is below 325 mesh (44 microns). Also, grinding tests were carried out in periods of 20 to 40 minutes to determine the operating parameter in the leaching. The leaching experiments were carried out in times of 24, 48 and 72 hours, to samples of the whole tail, with grinding of 40 minutes and with pyrometallurgical pretreatment (roasting), using a constant concentration of cyanide of 0.1% and calcium oxide at the 0.2% reaching a maximum silver dissolution of 69.19%. |
