Apr 25, 2018 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.

Effect of Initial Irrigation Conditions on Copper Heap

Effect of Initial Irrigation Conditions on Copper Heap

Heap leaching of ores is becoming a widespread method of metal recovery. It is common practice to initiate irrigation in heap leach facilities with low rates, followed by a gradual increase to the final rate. However, no detailed study has been performed to understand the processes that may lead to better recovery using this technique.
