How does gange differ from slag and tailings

In mining, tailings or tails are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) 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. WebJan 9, 2024 · When melt is poured into the cupple, gold and other metals will sink as silicates and other minerals rise to the top, forming slag. When these materials harden the gold can be easily separated from the slag. The slag frequently contains addition gold that can be recovered through reprocessing. Chemical Leaching
