Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores

Copper oxides are more abundant near the surface, but are considered low grade 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
