Copper is typically extracted from its ore through a process called smelting. This involves heating the ore in a furnace with a reducing agent such as carbon, which reacts with the copper oxide in the ore to produce pure copper metal. The impurities in the ore are removed as slag, leaving behind the pure copper metal.

Method of Copper Extraction
1. Mining:
- Copper is mined from open-pit mines or underground mines.
- Ore containing copper minerals is extracted from the earth.
2. Beneficiation:
- The ore is crushed and ground to separate the copper minerals from the waste rock.
- This involves processes such as flotation, where copper minerals float to the surface while waste rock sinks.
3. Roasting and Smelting:
- The copper concentrate is roasted to remove sulfur and other impurities.
- It is then smelted in a furnace to obtain molten copper called "blister copper."
4. Converting:
- Blister copper contains impurities, which are removed through a process called converting.
- Oxygen is blown into the molten copper to oxidize and remove impurities.
5. Electrolytic Refining:
- The molten copper from converting is further purified by electrolytic refining.
- Copper is deposited on cathodes as pure metallic sheets.
6. Casting and Rolling:
- The refined copper is cast into slabs or billets.
- These are rolled into sheets, rods, or other desired shapes.
