Heap Leaching and the Water Environment Does

Heap leaching can be a low cost means of treating low grade metalliferous ores, especially where the orebody is oxidised. Because heap leaching facilities have lower operational costs than conventional hydrometallurgical plants, heap leaching provides a potentially economic method of treating ores that might otherwise not be processed.
