What Is Copper Cathode?
Copper cathode is the final product of copper refining, produced through electrowinning or electrorefining. It serves as a raw material for manufacturing copper rods, wires, tubes, and alloys.
Key Properties of Copper Cathode
-
High electrical conductivity (100% IACS)
-
Excellent thermal conductivity
-
Corrosion resistance
-
Malleability and ductility
How Is Copper Cathode Produced?
The production of copper cathode involves multiple stages:
1. Mining and Crushing
Copper ore is extracted from open-pit or underground mines, then crushed into smaller pieces.
2. Concentration (Froth Flotation)
The crushed ore undergoes froth flotation to separate copper minerals from waste rock, producing copper concentrate (20-30% Cu).
3. Smelting
The concentrate is smelted in a furnace to produce copper matte (60% Cu), then converted into blister copper (98-99% Cu).
4. Electrorefining/Electrowinning
-
Electrorefining: Blister copper is purified into 99.99% pure copper cathodes.
-
Electrowinning: Used for oxide ores, where copper is extracted via electrolysis.
5. Final Product
The cathodes are shaped into sheets (typically 1m x 1m) and sold to manufacturers.
