technical requirements. As a result of this difference in business models, few copper mining companies are involved in any process further downstream than the refining of copper to cathodes. In addition, copper mining is tied to where the natural resource is available; copper fabrication to where products that use copper are made.
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 more frequently it is mixed with other minerals, some of which may have value themselves.

Oxide ore – treatment process: Copper is liberated from oxide ore through a chemical process known as leaching and solution extraction. The final step is electrowinning, which uses an electrical current to produce sheets of copper that are % pure and ready for shipping to world markets. Step 5. The copper is used in many applications
