What is SX-EW? Hydrometallurgical extraction is an effective way to recover copper from low-grade copper ores. But how is it done? Heap leaching is the method most commonly chosen for copper recovery from oxide ores. An acidic solution is used to leach the metal, dissolving the copper into what is referred to as a pregnant leach solution (PLS).
