  • Copper Mining and Extraction Sulfide Ores

    Laboratory electrolysis. In copper refining many anodes and cathodes are suspended alternately. All the cathodes are connected to the negative terminal and all the anodes to the positive terminal. Copper atoms on the anode surface lose two electrons becoming soluble Cu 2 ions. Cu 2 ions have a positive charge. They find themselves in an electric field between the electrodes.

  • Innovations Introduction to Copper Mining Extraction

     · Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels called adits to reach the ore. Underground mining is however relatively expensive and is generally limited to rich ores.
