  • LeachingMining Fundamentals

    Heap Leaching.The preprocessing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore. After preprocessing, the ore is leached with acid of alkali solutions to extract the metal. Heap leaching is carried out in the extraction of copper, nickel,
