Since copper production commenced in 2005, Sepon produced over 1.1 million tonnes of copper cathode. Sepon produces copper cathode using a whole-of-ore leach, sovent extract and electrowinning (SX-EW) process. Copper Cathodes are then transported via road and sea to manufacturers of cable, wire and tube in Asia. · The metal is transferred to the aqueous phase, called the pregnant leach Current status and limitations of copper SX/EW plants control 977 solution (PLS). After the leaching stage the solution contains impurities, which have to be removed. A simplified flow diagram of the process is shown in Figure 2.
