Spent ore is the material remaining after leaching. For example, copper or gold ore subjected to heap or dump leaching will become spent ore when recovery of the target metals is no longer economical. Usually left and reclaimed in place, a small portion of gold mines dispose of spent ore in piles or dumps.
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction 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 ...
Uranium-238, the most prevalent isotope in uranium ore, has a half-life of about 4.5 billion years; that is, half the atoms in any sample will decay in that amount of time. Uranium-238 decays by alpha emission into thorium-234, which itself decays by beta emission to protactinium-234, which decays by beta emission to uranium-234, and so on.
