How Copper is Extracted from Low Grade Ore
Heap leaching. Heap leaching is another common method used to extract copper from low-grade ore. The process involves placing the ore on a lined pad and then sprinkling it with a solution that contains sulfuric acid. The acid leaches the copper out of the ore and into the solution, which is then collected and processed to concentrate the copper.Web
