Copper Ore Leaching Sx

Copper Ore Leaching Processing

The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction SX. The SX process concentrates and purifies the copper leach solution so the copper can be recovered at a ...
