Tailings - Wikipedia
WebIn mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are different 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.
What are Tailings - Society for Mining, Metallurgy & Exploration
WebWhat are Tailings? Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed “tailings”.
