Twin Metals Dry Stack Tailings Storage 101 Dry stacking is the most sustainable method used to store filtered tailings—silty, sandy material— produced from the mine processing plant after the 4% of the ore that is copper, nickel and other metals is extracted. Tailings stored in dry stacks are piles of sand topped by native soil and vegetation.

tailings facilities and their consequence of failure. While not exhaustive, it illustrates the enormous volume of tailings that need to be safely managed. In 2001 Davies reviewed tailings facility failures up to that time and observed that all were predictable in hindsight and could have been prevented during the design and/or operational phase.

The following images show tailings deposition from a gold mine in the early 1900's in the Cortez Hills, Nevada, USA. The tailings have been deposited as a slurry from the processing plant (where the image was taken) and then flowed down the side of the valley creating extensive damage to the environment.

Upstream. Upstream construction begins with a starter dam. The tailings are then discharged into the facility where they form a tailings beach. The deposited tailings adjacent to the dam wall is allowed to drain and then can be compacted to be used to form the foundation for subsequent levels of the wall as the dam is raised.
