2 Recovery of Copper by Solution Mining Methods Solution mining replicates the natural process of oxidation and reduction, described above. Dilute acidic solutions are introduced to the copper-bearing ores, causing dissolution of soluble copper minerals (Table 1) remaining in the leached cap and underlying enrichment blanket.
The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies.
