lesser extent secondary copper sulphide ores, where leaching can be carried out at ambient temperatures. The microbially assisted generation of ferric iron, at typical mine ambient temperatures, allows the recovery of copper from secondary copper sulphides, while copper recovery from chalcopyrite is limited due to the slow leaching kinetics.
Recovery of Copper by Solution Mining Methods AZ
Recovery of Copper by Solution Mining Methods 3 Supplementing production from conventional heap leach operation, the inplace rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper. The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene
