Heap Leaching Copper Ore

2019-8-30  The leaching cycle on a lift of fresh ore is to be 60 to 90 days – the exact cutoff to be determined according to the acid and copper in the off-solution. Acid application during the leaching cycle is keyed to the acid content of the off-solution – the higher the acid coming off, the lower the acid applied. The initial leach

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.
