    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.Uranium Mill Tailings NRC.gov,Uranium Mill Tailings. Uranium mill tailings are primarily the sandy process waste material from a conventional uranium mill.This ore residue contains the radioactive decay products from the uranium chains (mainly the U-238 chain) and heavy metals.
