    How can you increase the copper recovery of your SX .

    Heap leaching is the method most commonly chosen for copper recovery from oxide ores. An acidic solution is used to leach the metal, dissolving the copper into what is referred to as a pregnant leach solution (PLS).This solution is collected and purified by solvent extraction (SX).

    The leach process is similar to that for gold, except that low cost sulphuric acid is used to leach the copper. Recovery involves concentrating the copper sulphate solution and removing impurities through the SX process, followed by precipitating the copper on the cathode in the electro winning (EW) process.
