Planning the Dewatering of a Tailings Storage Facility

Abstract The San Rafael mine in southern Peru produces over 10% of the world’s tin. decision was made to reprocess some its oldest tailings, due their volume and high tin concentrations. This tailing storage facility partially saturated required a dewatering process allow mining. paper describes conducted activities for this dewatering, including basic engineering studies focused on hydrogeological characterization recommended tests modelling define detailed design, developing an appropriate construction strategy. In addition, there were tasks associated with operating system, infrastructure maintenance, real-time follow-up implementation program monitor desaturation. system’s historical evolution, year beginning mining are reviewed.
