Skurski, P.E.,tailing heap leaching - payforwork.nl,Tailings Retreatment through Heap Leaching. The retreatment of tailings varies depending on the source of tailings and the material(s) to be recovered. The heap leaching and SX-EW processes have been key advancements in the ability to treat tailings heap leaching, in which ore is agglomerated and stacked on a heap and then irrigated with aHeap leaching - Wikipedia,Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from oreusing a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used i…

Tailings - Wikipedia

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.. The extraction of minerals from ore can be done two ways: placer mining, which uses water,,,
