Introduction
Copper extraction from its ore is a complex process involving multiple stages, from mining and crushing to concentration and refining. This flow chart provides a detailed breakdown of the copper extraction process, highlighting key steps and the equipment required—including Liming Heavy Industry’s high-efficiency crushing solutions.
Step-by-Step Copper Extraction Flow Chart
1. Mining Copper Ore
Copper ores like chalcopyrite (CuFeS₂), bornite (Cu₅FeS₄), and chalcocite (Cu₂S) are extracted via open-pit or underground mining techniques.
2. Primary Crushing
The ore is transported to a primary crusher, such as the Liming C6X Jaw Crusher (a high-capacity model for coarse crushing). This reduces large ore rocks into smaller pieces (typically 6–8 inches in diameter).
3. Secondary & Tertiary Crushing
For finer crushing, copper ore passes through:
- Secondary crusher: Liming HPT Cone Crusher (ideal for medium-hard materials).
- Tertiary crusher: Liming VSI6X Sand Maker or HST Cone Crusher for further size reduction (<25mm).
4. Grinding (Ball Mill/Powdering)
Crushed ore is ground into fine powder using a ball mill or Liming MTW European Trapezium Grinding Mill to liberate copper minerals from waste rock.
5. Froth Flotation (Concentration)
The powdered ore undergoes froth flotation, where chemicals separate copper-rich froth from gangue.
6. Smelting & Refining
- Smelting: Concentrates are melted in a furnace (producing ~99% pure matte copper).
- Electrolysis: Final purification via electrowinning yields 99.99% pure copper cathodes.
7. Waste Management
Tailings are processed to minimize environmental impact.
