  • Copper Mining and Processing: Processing Copper Ores ...

    Copper oxides are more abundant near the surface, but are considered lowgrade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are ...
