Abstract
A system and method are disclosed for improving component extraction from heap leach operations. Following heap leaching for some time, portions of the heap deficient in component extraction are identified, and treatment wells are drilled and remedial treatments are selectively performed on the identified portions of the heap. The remedial treatment can include hydraulically fracturing the identified portions of the heap followed by selective treatment with leach solution of the area impacted by the fracturing.
