Heap leaching a stack of gold - MiningFeeds
Heap leaching is used to extract gold, copper, silver, uranium, and iodine. This method was first employed to extract copper at the Bluebird mine in the US in the early 1960s, and then by several gold mines in the western parts of the US a few years later. Since then, heap leaching has been adopted successfully by many mines across the world.
