Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Cone crushers have been used as primary, secondary and tertiary crushers for quite a long time. They are widely employed for crushing hard and abrasive materials in both the aggregate and mining industries. Designed especially for the hardest material types, cone crushers are one of the best choices for crushing river gravel, basalt and granite, along with abrasive materials in the mining

This method is likely to be less costly than one involving the fine grinding of the whole ore.

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.
