Tailings - Wikipedia

Tailings - Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an oreTailings 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 .
