2. Heap Leaching. In this technique, the ore is arranged in large heaps. During heap leaching, an aqueous mixture of microorganisms is sprinkled over the leach pile. Then, the solution is collected and processed to help recover even metal. 3. In-situ Leaching. The ore remains in its natural state while the leaching process takes place.
Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are See for further information on the leaching process.
