Copper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The purification of copper is a form of recycling. Copper is purified further using electrolysis and we call it Copper Electrorefining (electrolytic refining). In industry this is carried out on a massive scale. The electrolytic copper production is processed in the huge copper electrolytic tank fulfilled with copper electrolytic solution. Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce 99.99% pure copper (whatever method is used to manufacture copper from its ore, its final purification is by electrolysis).
COPPER ELECTROLYSIS REFINING PLANT
Anode plates are hung by their "handles" in electrolytic copper refining tank. Pure copper cathode sheets suspended on solid copper bars are inserted into the same tank, one sheet between each anode. When an electric current is passed from the anodes through the electrolyte to the cathodes, copper from the anodes moves into the solution and is plated onto the starter sheet.Impurities from the anodes settle to the bottom of the tank.
COPPER ANODES(PLATES) CASTING MACHINE
The copper anode will be casting into anode plates in molds semi-automatically. After pretreatment removing of tin, lead, iron,aluminum starts charging of the copper material into the furnace which is followed by smelting process. When the impurities areremoved follows the slag removal and phase of reduction with natural gas. Reduction is aimed to remove the free oxygen. After the reduction the process is ended by casting, where the final product is casted into the form of copper anodes.
1. High current density, shorter anode distance, advanced technology make the electrolytic cycle much shorter.
2. Automatic controlling, compared with other processes, labor costs can be reduced by 50%;
3. The exhaust gas treatment system can produce useful chemicals, creating added value, after processing the tail liquid can be consistent with national environmental requirements;
