Heap Leach Pads are used throughout the world for mineral/metal harvesting in mine sites. Heavily engineered for long-term success, these sites become literal mountains seen for miles holding hundreds of thousands of metric tons of mined ore that is then soaked with sulfuric acid or cyanide to extract the precious minerals.
