What The Type Of Copper Ore In Chile And The Process Used

2 the copper is recovered directly from the ore using a solvent extraction-electrowinning sx-ew process. crushed ore is placed in low heaps built on sloping impermeable pads for heap leaching and the metal dissolved by repeated application of sulphuric acid solutions. the pregnant solution is collected for copper recovery by electrowinning.
