    Leaching Mining Fundamentals

    Heap leaching is also known as acid leaching. This method is most effective for the extraction of metals from difficult ores, and is one of the most tried and tested methods. The pre processing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore.
