Filtered Dry Stacked Tailings – The Fundamentals
Filtered tailings are becoming an increasingly common consideration for tailings management at many mines There are more filtered dry stack tailings storage facilities than there are surface paste facilities yet the amount of guidance documentation on filtered tailings is virtually nonexistent in compare to those same paste tailings facilitiesWhile thickened and paste tailings may be able to achieve beach slopes in the 3 to 6 percent range, dry stack tailings may be stacked with stable slopes in the 20 to plus30 percent range, with compaction This paper presents the primary geotechnical considerations for the design of dry stack facilitiesDry Stack Tailings – Design Considerations IQPC CorporateDry stack tailings, also known as filtered tailings, represent a modern approach to tailings management in mining operations Unlike traditional wet tailings, where tailings are mixed with water and stored in ponds, dry stack tailings involve dewatering the tailings to remove excess moisture before stacking them in a controlled mannerDry Stack Tailings Process Clean TeQ WaterDry stacking is the most sustainable method for the management of filtered tailings Conventional tailings storage methods incur costs postmine closeout due to maintenance; DST areas can be rehabilitated and blend with the Dry Stack Tailings Management TAKRAF GmbH
