After scrap copper is melted, refined and cast into anode plates, the next step is electrorefining.
This is where the Copper Electrolysis Plant takes over.
From anode plates entering the tankhouse to finished cathode copper leaving the line, the process includes electrorefining, plate handling, cathode stripping, conveying and stacking.
For us, these are not separate machines or separate steps. They need to work together as one production process.
1. Anode Plates Enter the Electrorefining Tankhouse
After fire refining and casting, the anode plates are transferred to the electrorefining tankhouse.
Anode plates and cathode plates are placed in the electrolytic cells. During electrorefining, copper from the anode dissolves into the electrolyte and is deposited onto the cathode.
At this stage, stable electrical contact, plate positioning, electrolyte circulation and daily tankhouse operation all affect the refining process.
For large-scale production, plate handling also becomes an important part of the production cycle.
2. Moving Plates Through the Tankhouse
Every electrolysis cycle involves the movement of a large number of anode and cathode plates.
The plates need to be lifted from the cells, transferred to the required position and sent to the next process. After processing, reusable cathode plates also need to return to the electrolysis cycle.
For this reason, plate handling should be considered together with the cell arrangement and downstream equipment.
In larger tankhouses, dedicated lifting and handling systems can move multiple plates at one time, reducing repeated manual handling and helping the production cycle run more smoothly.
3. From Cathode Plate to Finished Copper
After the electrolysis cycle is completed, the deposited copper is separated from the permanent cathode plate.
This part of the process can involve cathode stripping, plate transfer, copper sheet conveying and stacking.
For projects with higher automation requirements, robotic handling can be added to reduce repetitive manual work and connect the stripping and stacking processes.
After stripping, the cathode plates return to the electrolysis cycle, while the copper sheets continue to the finished product area.
4. Connecting the Whole Process
In an actual Electrolytic Copper Refining Plant, the performance of one machine is not enough.
The electrolysis cycle determines when plates need to be handled. The handling system needs to match the stripping capacity. After stripping, conveying and stacking also need to keep up with production.
This is why we look at the complete route when working on a copper electrorefining project:
Anode Plate → Electrorefining → Plate Handling → Cathode Stripping → Conveying → Stacking → Finished Copper Cathode
The equipment and layout are configured according to the customer’s plant capacity, plate specifications, automation requirements and actual operating conditions.
The aim is practical: reduce unnecessary handling, keep the different processes matched, and make the tankhouse easier to operate.
Copper Electrolysis Plant for High-Purity Copper Production
Our work focuses on the electrorefining section after anode casting, including electrorefining systems, permanent cathode plates, plate handling systems, cathode stripping machines, conveying, stacking and related automation.
For projects targeting high-purity cathode copper, including 99.999% high purity copper where supported by the overall refining process and operating conditions, the complete tankhouse needs to work as one production system.
From engineering and equipment selection to installation and commissioning, we work around the customer’s actual production requirements rather than treating each machine as an isolated piece of equipment.
