Copper Heap Leaching & SX-EW Slideshow - MineralsEd
2019-2-27 · 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.
