Heap leaching of copper

A method of leaching copper from a heap of ore that includes at least one resting step followed by an irrigation step, wherein, during the irrigation step a leach solution that contains chloride ions is applied to the ore at a higher rate than during the resting step.

mining

Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components Crushed ore is stacked on a leaching pad and irrigated with the leaching agent. The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap.
