Heap leaching SX-EW is a method of extracting pure copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond.

Crushed ore heap leaching (of secondary sulfides) consumes approximately half the energy of milling-flotation-smelting process - Overall resource utilization is less efficient - 75 vs. 87 copper extracted ROM stockpile leaching - Similar energy efficiency to crushed ore heap leaching, based on ore.
As high-grade copper ores are depleting globally, this approach is economical and facile and has, hence, received considerable attention among copper extraction experts. Among different applications of heap leaching, copper extraction from its oxide ores has been relatively less explored for a long time, except for a few reports [14,15].
Efficient recovery of mineral resources from ore heap leaching requires good ore permeability to optimize metallurgical recovery. Solution and air (in the case of copper sulfide ores) need to move.
Microcracks in HPGR materials result in improved penetration of leach solution into the grains and thus metal recovery. The objective of this work is to develop a better understanding of ores crushed by HPGR and cone crusher, in terms of microcracks and PSD, and assess the benefits of using HPGR for heap leach.
