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.
Mining involves the removal and processing of ore—the rock containing economically recoverable amounts of desired metals. To access the ore deposits, waste rock must be removed and stored in waste rock dumps, and after processing, mine tailings may be produced and stored in engineered tailings storage facilities (TSFs).
