Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
A breakthrough technology using high-pressure membrane systems allows the condensing of tailings into large blocks, which can be stacked to reduce footprint and no longer pose the risk of seepage into natural water sources. This long-term, low-energy storage can be achieved with Pure Aqua Ultrafiltration Systems. MINING INDUSTRY SOLUTIONS

In cases where mining does not require backfilling of stopes, storing tailings back in underground mine voids is a rather expensive exercise and is commonly avoided. However, following a number of tailings dam failures, mine planners have started considering the idea of underground permanent storage.
