  • Copper Production in Zambia in Five Mining For Zambia

    Oxide oretreatment 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
