In-situ recovery, or ISR, is an approach to mineral extraction which combines drilling, rock fracturing and chemical leaching directly at the drill site, creating minimal surface disturbance of the landscape. Sometimes called in-situ leaching or solution mining, ISR initially involves drilling holes into the ore deposit.

Leaching solutions (or lixiviants) used in heap leach mining are either highly alkaline such as sodium cyanide, or highly acidic such as sulphuric acid. To ensure uniform distribution of the lixiviant to the ore heap and to minimize evaporation, drip irrigation systems are the preferred distribution method.

Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. …
