    Tailings deposited into dams are in the form of a slurry. In 1998, a tailings dam failed at the Los Frailes zinc mine in Spain, causing more than one billion gallons of acidic, heavy metalladen sludge to spill into the surrounding area, eventually making its way into the Guadiamar River. The spill decimated the area, resulting in massive ...

  • What are Tailings?

    Jul 03, 2018 · Tailings are materials that are left after the dissociation of the valuable portion of materials from ores. Tailings can be extracted through placer mining or hard rock mining. This can be most commonly found in mills in its slurry form. Tailings are fine waste that can be found floating in water and can cause environmental damage or corrosion.

    Traditional deposition of tailings slurry in a tailings storage facility (TSF) can create risks of dike failure. In order to minimize these risks and slurry spillage, the surface deposition technique of densified tailings (DT) through dewatering of the slurry has emerged. The DT technique has the potential to maximize water reuse, improve the shear strength of surface tailings, and reduce the ...
