Tailings WikipediaArtificial neural networks for optimization of gold
Tailings also called mine dumps culm dumps slimes tails refuse leach residue slickens or terra cone terrikon 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 In this way gold silver alloys are obtained by pyrometallurgy In the smelting process slag compositions essentially determine the amounts of gold left in slag hence the recovery of gold To maximum the recovery of gold it is of great importance to optimize the slag composition so as to minimise the gold content in slag
