Learn About the Heap Leaching Process & Mining Techniques
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.
Optimal design and planning of heap leaching process ...
Although the process of heap leaching is an established technology for treating minerals, such as copper, gold, silver, uranium and saltpeter, as well as remediating soil, no studies to date have investigated process optimization. This work presents a methodology for the design and planning of heap leaching systems to optimize the process.

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 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 ...
Aspects of Design and Operation of Heap Leach Pad and ...
Heap leach pads are composed of mined ore, usually crushed, disposed on drainage system to be processed with leach solutions. In the case of dynamic heap leach, after the leaching process, spent ore is transported by conveyor belts to be disposed into dumps. It is common to observe physical stability problems in these dumps, that could ...
