Copper processing Copper processing Ores Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but frequently it is mixed with other minerals, some of which may have value themselves.

7. Sulfide Ore Refining. The final step in processing sulfide ore copper from the smelter is to make high purity copper cathodes. 8. Copper Products Many Uses. Copper cathodes are pure copper produced from the processing of copper ores. However, cathodes are not in the final form of usage as copper.
By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on site.
