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 ...

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns.

Nov 29, 2019 Heap leaching is one of the oldest and the most traditional mining process used to extract valuable metals from specific minerals. This is a hydrometallurgical process in which the solution is applied for the dissolution of minerals from the ore that is used for the extraction of metals. Originally, heap leaching was practised 500 years ago.

Nevada was the "birthplace" of modern gold heap leaching in the late 1960's, and is only now giving up its dominance of this technology. Other very large gold districts - notably the pre- cambrian shield areas of Canada, Australia and South Africa - show relatively few heap leaches.
Mintek has developed considerable experience in heap leaching and heap bioleaching, and has undertaken an advanced research programme investigating the high-temperature heap bioleaching of low-grade chalcopyrite. This has culminated in the design, commissioning and operation of the copper heap bioleaching pilot plant shown below.
