Ti Anodes for Zinc Electrowinning
PRS titanium-based multi-element composite anodes redefine efficiency in zinc electrowinning (EW), outperforming traditional graphite and lead-silver anodes. Designed for high-fluoride, high-chloride environments, our anodes deliver longer lifespan, higher zinc purity, and minimal maintenance—ideal for zinc EW plants aiming to reduce costs and boost productivity.
Advantages of PRS Ti Anodes
Performance Metric | Traditional Anodes (Graphite/Lead-Silver) | PRS Titanium Anodes |
Service Life | ~0.5 years | ~1–1.5 years (2–3x longer) |
Fluoride/Chloride Resistance | Low (prone to degradation) | 200%+ improvement (handles Cl⁻/F⁻ ≤ 500 mg/L) |
Current Efficiency | Unstable (often <85%) | Stable ~89% |
Zinc Purity | Variable (below Grade 1#) | High (Grade 0#: Zn99.995; Grade 1#: Zn99.99, ASTM B6 standard) |
Maintenance | Frequent cleaning/ replacement (high labor) | Almost no maintenance; low on-site labor intensity |
Power Consumption | Higher (due to low efficiency) | Reduced by 3% (vs. traditional lead-silver anodes) |
