Heap leaching - Wikipedia
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of stone 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 ...

The heap leach pad working inventory of 3 Mt at 0.72 g/t gold and 8 g/t silver containing 0.07 Moz of gold and 0.8 Moz of silver. The heap leach pad is considered to be a working inventory because the active ore placement lift has a planned 150-day leach cycle to realise of the estimated total recovery.

Equinox Gold - Castle Mountain
The Castle Mountain heap leach gold mine produced more than one million ounces of gold from 1992 to 2004, when it was shut down due to low gold prices. With more than 3.5 million ounces of gold reserves remaining, Castle Mountain will be a long-life low-cost gold mine producing 2.8 million oz of gold over a 16-year mine life.
Heap leaching a stack of gold | MiningFeeds
Heap leaching requires less aggressive techniques: a stone 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.
Learn About the Heap Leaching Process & Mining …
Heap leach mining is an industrial hydrometallurgical process, where the metal contained in an ore body is extracted by dissolution. The target mineral is leached with an aqueous solution whereby the mineral is dissolved into what is called a “pregnant” solution which, is then captured and later recovered downstream in the processing line.
