In the demanding environment of zinc electrowinning, the choice of anode material directly impacts productivity, operational costs, and product quality. PRS Titanium Anodes represent a breakthrough in electrochemical engineering, offering exceptional durability, efficiency, and compatibility with high-impurity electrolytes. Here’s why leading zinc producers are making the switch.
Why PRS Titanium Anodes Outperform Traditional Materials
1. Extended Lifespan
1–1.5 years service life vs. 6 months for lead-silver or graphite anodes.
Reusable titanium substrate reduces long-term replacement costs.
2. Superior Corrosion Resistance
Tolerates Cl⁻ ≤ 500 mg/L and F⁻ ≤ 300 mg/L – ideal for challenging electrolytes.
200% improvement in fluoride/chloride resistance compared to lead anodes.
3. Enhanced Current Efficiency
Average 89% current efficiency in operational feedback.
3% higher efficiency than lead-silver anodes, reducing power consumption by 3%.
4. High-Purity Zinc Production
Enables consistent Grade 0# Zn (99.995%) and Grade 1# Zn (99.99%) output.
Minimal anode slime prevents cathode contamination.
