1. The procurement cost can be reduced by 4%.

2. Output rate of grade A copper is 100%.

3. The electric current efficiency can be increased by 3% ~ 10%.

4. Cell voltage can be reduced by 0.05V ~ 0.10V.

5. The current density can be increased to 350-500A/m² during the copper EW process.

6. The copper production capacity is increased by 3% ~ 10%.

7. The DC current cost is reduced by 200 ~ 300kWh/ton of copper.

8. The oxygen on the surface of the fence-type anode plate easily forms small bubbles, and when the bubbles rise to the liquid surface, they bring out less acid mist.

Fence-type anode v.s. Traditional anode

The fence-type anode is a specialized aluminum-based lead-alloy composite developed to improve the limitations of traditional lead-alloy anodes. It has been in large-scale use since 2014 in zinc and copper electrowinning industries, showing substantial efficiency gains. Specifically, the fence-type anode improves current efficiency by over 3%, reduces cell voltage, and enables higher current densities. Its industrial success has been proven in African markets such as the DRC and Zambia, with a lifespan exceeding five years, consistent performance, and no need for additional equipment. Its ability to enhance electrolyte flow and copper ion transfer leads to the production of high-purity copper, and it has become a preferred choice in major projects, significantly boosting production capacity.

Compared to traditional lead-based alloy anodes, current efficiency increased by more than 3%, and cell voltage decreased by 0.05–0.10V. The current density during copper electrowinning increased to over 350–400A/m², whereas the traditional lead-alloy anode plate’s current density is generally 250–300A/m².
The fence-type anode plate does not require any additional auxiliary equipment during use, does not deform, improves electrolyte flow, enhances the transfer speed of copper ions, and ultimately increases the current efficiency of copper electrowinning, producing high-purity copper.
