Heap leaching is one of the oldest and the most traditional mining process used to extract metal ions using chemical reagents, so the metal ions are released from the mineral . The output of,Heap leaching as a key technology for recovery of values,,Uranium heap leaching has been pioneered since the 1950s, whereas both, copper oxide and gold/silver heap leaching emerged in the US from the late 1960s (Kappes, 2002; Bartlett, 1998). Large scale copper heap leaching commenced in Chile from the 1980s, and sulphide heap leaching emerged essentially as a consequence of acid leaching from mixed,A Brief Note on the Heap Leaching Technologies for the,,provide information on the applications of a unique and versatile heap leaching process for rare earth extraction and to highlight the advantages and limitations of this process. 2. Heap Leaching of Mines Industrial mining processes are the activities involved in the extraction of metals or minerals.
