High Light: Electrolytic Silver Recovery System 99.99% Purity, 99.99% High Purity Silver Extraction Machine, 99.99% Electrolytic Silver Extraction Machine。
99.99% high-purity silver electrolysis machine
The silver electrolysis equipment produced by our company is the most advanced and efficient at present. We use the crude 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 dissolve the crude silver in the anode, and the pure silver precipitates in the cathode to improve the purity of silver, so as to refine the crude silver containing more than 97% silver to 99.99% high-purity silver.
The biggest advantage of product design:
1. A flue gas condensation system is set to cool the flue gas to avoid silver loss;
2. The main material of the equipment is high performance polypropylene material, adding anti-aging agent in the material, so that the service life of the equipment is greatly extended. The overall support is made of PPH with strong corrosion resistance; The cathode and anode conductive strips are made of titanium clad copper with excellent conductivity.

Recovery Of Gold By Displacement With Copper WireRecovery Of Gold By Displacement With Copper WireRecovery of gold by displacement with copper wire (or copper chips) under heating. For gold-containing chloride waste solutions, copper wire (or copper chips) are generally used to recover gold by displacement under heating.
In addition, the electrolytic method can be adopted to recover gold from waste plating solutions with high gold content, while for waste solutions and washing water with low gold content, activated carbon adsorption and ion exchange adsorption methods are available to recover gold.

Recycling Method for Noble Metal LinersRecycling Method for Noble Metal LinersCleaning and Recycling Method for Noble Metal Liners In the manufacturing process of semiconductor chips, the cleaning and recycling method for noble metal liners proceeds as follows: first, the environment-friendly gold-leaching reagent solution and alkaline agents are purified, followed by complete dissolution of the surface gold plating.
Next, dissolution of other plated metals is conducted to complete the stripping of the plating layers; finally, gold is extracted and recovered, and the liner substrate undergoes ultrasonic non-destructive cleaning. The liner substrate is then dried under vacuum, and after passing the surface appearance quality inspection, it is packaged in vacuum and stored in the warehouse.
This method features the advantages of achieving noble metal recovery without damaging the liner substrate, simple and efficient operation, and safe and environmentally friendly working procedures.

Gold Recovery From Gold-bearing Waste LiquorsGold Recovery From Gold-bearing Waste LiquorsGold-bearing waste liquors include electroplating waste effluents, which are mainly composed of waste cyanide gold plating solutions, waste ammonium gold sulfite gold plating solutions, aqua regia etching waste liquors, chlorination waste liquors, and various gold-bearing rinse waters.
Electroplating waste liquors have a relatively high gold concentration: that of acidic gold plating waste liquors generally ranges from 4 to 12 g/L, while the concentration of alkaline gold plating waste liquors can reach up to 20 g/L.
Available methods for gold recovery from gold-bearing waste liquors are as follows:
(1) Recover gold from cyanide gold-bearing waste liquors via the zinc (aluminum) cementation process, using zinc wire or zinc powder as the precipitant.
(2) Recover gold from waste ammonium gold sulfite gold plating liquors via the pH adjustment method.
(3) Recover gold from aqua regia etching waste liquors.
(4) Recover gold via heated cementation with copper wire (or copper turnings) as the precipitant.
