— 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. ... In this process copper concentrate is fed into the smelter with oxygen ...
