  • How copper dump leaching works ScienceDirect

    · In dump leaching, most of the dissolved copper would initially come from the upper parts of the ore bed, where the fines are concentrated At first, the ore near the bottom would contribute less dissolved copper due to the lack of fines Over time, however, both the leaching action and the weight of ore pressing from above would result in the continuous breakage of that coarse mineral ThatDump leaching being a quantum leap carries a higher risk than heap leaching where the ore is crushed In addition, there was little experience in Australia with dump leaches This paper describes the process that was undertaken so funding could be provided, and discusses Effect of ore size and heap porosity on capillary process Heap leaching is an industrial mining process used to extractdump leaching gravityDefine Heap and dump leaching facilities means all land forms, structures, equipment, and material that contact, process, contain, collect, or confine leaching solutions associated with the hydrometallurgical processing of heaps and dumpsHeap and dump leaching facilities Definition | Law Insider
