Advanced Preparation Techniques
The production of high purity copper metal involves some methods designed to eliminate impurities with precision
Electrolytic Refining
Crude copper undergoes a purification process in an electrolyte. Impurities settle in the anode mud while pure copper is deposited at the cathode, achieving the desired purity.
Zone Melting
By making use of the solubility differences of impurities between solid and liquid phases, impurities are concentrated at one end during multiple smelting cycles, resulting in ultra-pure copper.
Vacuum Smelting
Copper is heated in a vacuum to prevent oxidation and effectively remove impurities, yielding high-purity results.
These innovative techniques ensure that the final product meets the rigid demands of high-tech applications.
