Leaching Mining Fundamentals

Heap Leaching. 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. After pre processing, the ore is leached with acid of alkali solutions to extract the metal. Heap leaching is carried out in the extraction of copper, nickel,
