Heap leach processing, though rare in global copper supply due to limited oxide or leachable copper deposits, provides several benefits. It reduces water usage, utilizing approximately 10% of the water that traditional flotation plants use. It is also more efficient in material movement, resulting in lower total carbon intensity.
