Tailings - Wikipedia

Tailings. 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.

Chemical risks in mining industry? - PREVOR

Tailings generally contain small amounts of the valuable mineral(s) not completely recovered during beneficiation ; some unwanted or undesirable deleterious minerals; and some of the chemicals that may have been used in the course of the separation process. Underground mines may use these tailings to backfill mining-created underground voids.
