Recovery of Copper by Solution Mining Methods

2015-7-23  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 copper sulfides, inadequate contact of the leach solutions with soluble copper minerals (i.e. channeling) and poor oxygenation (O’Gorman et. al, 2004).
