Titanium Anodes for Copper EW
PRS presents high-performance titanium-based lead dioxide (Ti/PbO₂) anodes, tailored to address the pain points of traditional anodes in copper electrowinning processes. Our anodes deliver superior stability, efficiency, and cost savings, empowering copper EW plants to enhance production quality and operational safety.
Advantages of PRS Titanium Anodes
|
Traditional Lead Anodes |
PRS Titanium Anodes |
|
Service life: 1–3 years |
Service life: Increased by 50%+ (vs. traditional) |
|
Current efficiency: 80–85% |
Current efficiency: 91–94% (3%+ improvement) |
|
Lead dissolution causes product contamination |
Lead dissolution rate reduced by 99% (high cathode purity) |
|
Prone to deformation/short circuits; needs manual straightening |
Dimensionally stable; no deformation/short circuit risks |
|
Requires frequent cell bottom cleaning (high labor cost/health risks) |
Minimal anode slime; no regular cleaning needed |
|
Higher energy consumption (more cells for target output) |
DC power consumption reduced by ~110 kWh per ton of copper |

Customer Success Verification
Since June 2019, a copper EW plant has procured 2,000 PRS Ti/PbO₂ anodes, with operational data confirming:
- Current efficiency boosted to 91–94%, exceeding traditional anodes by 6–14 percentage points.
- Energy savings of ~110 kWh per ton of copper, cutting overall power costs.
- Zero anode deformation or lead contamination; all metrics meet contractual standards.
- Reduced maintenance labor by 80% (no anode straightening or cell cleaning required).
