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 99.99 pure and ready for shipping to world markets. Step 5. The copper is used in many applications

Copper mineralisation at Kansanshi occurs as both vein-hosted mineralisation, and to a lesser extent sediment-hosted mineralisation. Later breccia-hosted and supergene mineralisation have overprinted all previous mineralisation styles. Chalcopyrite is the main ore mineral for both vein-hosted and sediment-hosted mineralisation styles.
