Tailings Water Management Considerations for Conventional …

The risk of physical instability for a conventional tailings facility can be reduced by having good drainage and little (if any) ponded water. Simply put, ''no water, no problem''. Water management of a tailings facility not only involves the superficial water flows but the interception, collection and treatment of seepage.

Tailings

In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction ( gangue) 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.
