In dump leach operations, copper bearing ore mounds, typically created by "dynamiting" an ore deposit, are sprayed with a sulfuric acid leach solution. The leach solution dissolves the copper oxides. Upon recovery, the leach solution is subjected to copper recovery operations (solvent extraction and electrowinning).
