While 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 plus 30 percent range, with compaction. This paper presents the primary geotechnical considerations for the design of dry stack facili ties.
Mar 21, 2012· Dry Stack Tailings Overview. Tailings Slurry n Least water conservative. Thickened Tailingsn Dewatered material but still a slurry.n Better water conservative than slurry. Paste Tailingsn Dewatered, but still a slurry (100% saturated)n Better water conservative than thickened. Filtered Tailingsn Most water conservative.
The Outotec Dry Tailings Plant is a fully integrated design that comprises thickening, filtration, and dry material handling for tailings dry stacking, including all necessary ancillary equipment and systems. This plant is particularly suited to areas where water consumption is a sensitive issue, or where there are strict requirements in terms of the safe operation, tailings management, and eventual mine closure and rehabilitation. Optimized footprint of tailings storage
