  • Copper Mining and Extraction: Sulfide Ores

    Copper Mining and Extraction: Sulfide Ores

    Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.
