    At some Australian mines, the copper is leached from the ore to produce a copper-rich solution which is later treated to recover the copper metal. The ore is first broken and set out on leach pads where it is dissolved by a sulfuric acid solution to leach out the copper. The copper-rich solution is then pumped to the solvent extraction plant to separate the copper as a copper complex. This is ...
