The pregnant solution containing the dissolved copper flows by gravity to the solvent-extraction plant. Solvent extraction mixer-settlers recover 90% of the copper from the pregnant leach solution. The remaining 10% is recycled to the heap leach. The run-of-mine dump leach material is further leached on the old sulphide ore pad.

The crushed ore is then taken to the agglomeration plant, where sulphuric acid and raffinate are added. Copper-bearing rock is then conveyed to the heap leach pad, which leaches the ore in two stages. In the first stage, the ore is leached using intermediate leached solution (ILS). In the second stage, the ore is leached further using raffinate.
