Dump and Heap Leaching

As ore gangue minerals react with leach solutions, deg-radation or decrepitation of rocks can occur, resulting in more fines being produced. These fines will change the regional per-meability of the heap (Bartlett 1998). Normal heap leach operations have a wide distribution of ore particle sizes and uneven ore mixing, so there will be
