Tailings Dam Questions and Answers Casino Mining Corporation

Why do we need tailings dams? Tailings dams, or tailings management facilities (TMF), are required for the long term deposition of mine waste such as tailings and waste rock. Tailings are generated from the mined ore that has been ground during mine processing, and must be kept behind a dam to prevent them from.

Tailings dam Wikipedia

The mining and processing byproducts collected in tailings dams are not part of the aerobic ecological systems, and are unstable. They may damage the environment by releasing toxic metals (arsenic and mercury among others), by acid drainage (usually by microbial action on sulfide ores), or by damaging aquatic wildlife.
