In the "vat leach" process planned for Pascua-Lama, ore is pulverized and poured into enormous vats. Sodium cyanide solution—the annual use of a typical mine is measured in hundreds of tons—is mixed with the pulverized ore. Cyanide trickling through the ore collects gold and silver particles, forming water-soluble gold– or silver–cyanide compounds.
