    Tailings - Wikipedia

    Tailings 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 being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water ...

    Uranium tailings result from the mining and processing of uranium bearing ore above a defined cut-off grade. The ore is typically reduced to sand and silt sizes by initial crushing followed by fine grinding. It is then subjected to further processing that involves acid or alkaline leaching to chemically extract the uranium.
