Besides ISR processing, gold recovery can be achieved by heap, dump or vat leaching. In heap and dump leaching, which are usually used to treat low-grade ores (0.5–1.0 g/t), mined ore is placed on leach pads, which are irrigated with lixiviant and the solution is recovered for further processing and gold recovery.
