WHAT IS HEAP LEACHING?

etc Heap leaching does not require fine grinding and large processing plants Additionally as heap leaching does not require a tailings dam to contain spent ore from the processing plant it is easier to rehabilitate post mining Upon closure of the mine the heap leach is rinsed with clean water until testing demonstrates that there are no

Precious Metal Heap Leach Design and Practice

Mining of ore for heap leaching employs the same techniques and equipment as mining of ore to feed any other process method Where uncrushed ore (run-of-mine ore) is placed on the leach pad ore may be blasted very heavily in order to reduce rock size and improve gold recovery In high-rainfall environments when processing clay-rich material it is very important to practice a mining routine
