Backfilling the tailings are usually combined with a binder like cement, then used to fill voids in the underground operation. This is widely considered the safest form of tailings disposal. 2. Dry stacking– the tailings are dewatered, or “filtered”, after mill processing. The resulting tailings are See more on earthworks

  • What are tailings dams? IndustriALL

    Rather than reinforced concrete, tailings dams use earth or rock to create a barrage. However, most tailings dams use the cheaper but more dangerous upstream method of construction, using the tailings themselves to create a barrier. The dam is then continually raised to accommodate more waste. These dams are more unstable and more prone to leakage.
