What makes hydraulic dewatered stacking stand out? 

Improved tailings stability

Simply and effectively dewater tailings in line with GISTM best-practice tailings management guidelines.

  • Dewatered and well-consolidated tailings are safer and more stable, eliminating the risk of liquefaction and catastrophic mudslides in the event of a TSF failure.


Future-ready water management 

Tailings water recovery of 75% achieved so far. 

  • Hydraulic dewatered stacking lowers fresh water draw and/or desalination requirements, enhancing water stewardship in a water-scarce region. 



Simplified and faster closure 

Take a progressive approach to closure and expedite final hand-over.

  • Risk of re-saturation and water contamination is controlled, even after closure, while long-term subsidence is likely lower as HDS tailings consolidate quickly, as they are deposited.
