    Iron oxide ores usually follow a processing path where the copper is leached from the surrounding rock. The ore is first heaped into piles in special leaching areas, and a sulphuric acid solution is sprayed over the heap to gradually dissolve the copper, separating it from the surrounding gangue. The copperrich liquid is collected in pools and pumped into a plant for refining. An organic
