Electrolytic & Electrowinning Equipment

High-Current Density Silver Electrolytic Cell

Patent Number: ZL2019 2 1555230.9 The silver electrolytic unit is a device designed to refine crude silver (with ≥97% silver content) into 99.99% pure silver through electrolysis. It utilizes a crude silver plate as the anode, a titanium plate as the cathode, and a silver nitrate (AgNO₃) solution as the electrolyte. When a direct current (DC) power supply is applied, the crude silver dissolves at the anode, while pure silver deposits onto the cathode, achieving the purification effect.

Advantages of the Silver Electrolytic Unit

  1. Cathode Current Density: 750 A/m²
  2. One-Piece Electrolytic Cell Design: Eliminates electrolyte leakage risks.
  3. Electrolyte Cooling and Temperature Control: Maintains optimal operating conditions.
  4. Stable Product Quality: Electrolytic silver powder consistently achieves ≥99.99% purity.
  5. Transparent Enclosed Fume Cover with Side Exhaust: Ensures a clean and safe working environment.
  6. Electrolyte Cooling System: Reduces electrolyte volatilization and minimizes acid consumption.
  7. Fume Condensation System: Cools exhaust gases to prevent silver loss during processing.
  8. Material Specifications: The main cell body is constructed from high-performance polypropylene (PP) reinforced with anti-aging additives, significantly extending its operational lifespan, while the integrated support frame is made of PPH material, demonstrating exceptional corrosion resistance for long-term durability. Both the anode and cathode busbars utilize titanium-clad copper, ensuring superior electrical conductivity and reliable performance in electrolytic applications.
