Dry stack tailings, also known as filtered tailings, represent a modern and safer method of tailings management. Rather than mixing tailings with water and storing them in conventional pond-style impoundments, this approach dewaters the tailings lowering their moisture content significantly before stacking them in a stable, controlled formation(Dry Stack Tailings Process | Clean TeQ Water, 2023).
In the dry stack method, tailings are compacted into solid mounds and simultaneously reclaimed with native soil and vegetation. This approach removes the need for containment dams eliminating the risk of dam failure and sidelining long-term storage liabilities. Additionally, thanks to the underlying geology, these tailings are non-acid generating, ensuring an environmentally stable outcome(“Dry Stack Tailings Storage,” n.d.).
What’s one key benefit of dewatering tailings (like water recovery or faster reclamation) that you find most impactful? Let’s discuss!
