Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an 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
The process of treating gold ore to extract gold (and silver) and, therefore, produce bullion is called milling. The building housing the process is called a mill. The finely pulverized material that is rejected from the mill after the gold has been extracted is called tailings.
