Situ Leaching - an overview | ScienceDirect Topics

Comparatively, copper recovery from porphyry deposits using ISL is on a much lower scale. San Manuel “in situ” mining in Arizona reported copper recoveries in the range of 50%–60% over a period of 5 years. Copper was recovered through this method at ASARCO’s Silver Bell Copper mine in Arizona from fragmented ores.
