Dry Stack Tailings are becoming an increasingly viable and attractive alternative to tailing impoundments in the mining industry. A Filter Press delivers some of the best results from competing dewatering technologies. By dewatering tailings to a relatively “dry cake,” this stable and stackable form of storage is ideal for mining companies.

3.1 Tailings Facility Liner and Underdrain System. The key components of the seepage control system for the filtered tailings storage facility consists of: A geosynthetic double liner system installed over the footprint of the tailings storage area. This consists of an upper textured HDPE layer, a leak detection system and a lower GCL layer.

Dry Stack Tailings. Dry 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
