Heap 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

Heap leaching a stack of gold MiningFeeds

Apr 25, 2018· Heap leaching requires less aggressive techniques: a chemical solution is simply sprayed on heap ore. As the solution percolates through the heaped ore, it dissolves the gold. The solution is then collected and treated further by adsorption. The heap leach stack must be porous enough to allow the solution to drip or to drain through the stack.
