refine crude silver tank

Our company's silver electrolysis equipment uses electrolysis to refine crude silver containing more than 97% silver to 99.99% high-purity silver. The production principle is to use the coarse silver plate as the anode, the titanium plate as the cathode, the silver nitrate solution as the electrolyte, and then connect the DC power supply to realize the purification by dissolving the coarse silver in the anode and precipitating the pure silver in the cathode.
Advantages of our equipment:
1. The most efficient current density electrolysis process is adopted, with cathode current density of 750A / m2 and high production efficiency;
2. The product quality is stable, and the purity of electrolytic silver powder can reach more than 99.99%;
