    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 ...

  • Ore grade - - Moneyterms: investment, finance and

    Mill head grade is the grade of mined ore fed into a mill, as opposed to the grade of the ore mined. The grade of ore from a mine changes over time. A lower grade will (other things being equal) mean a higher cost per unit weight of extracted metal. Costs are also influenced by other factors such as the costs of the actual mining of ore itself. The most important factor in the profitability of ...
