Silver Electrolysis Refining Machine

 

The machine function is refining 80% silver bars or old 90% silver Jewelry to 99.9% silver or 99.99% silver.

Anode: 80%~90% purity silver        Cathode: Titanium cylinder          Electrolyte: 10% nitric acid solution

Working principle

The machine uses 80%~90% silver ( put the silver into the four round titanium basket) as the anode, the titanium cylinder as the cathode, and 10% dilute nitric acid as the electrolyte.

during the working of the machine, the silver will be dissolved in the dilute nitric acid solution, and then by electrolysis,   the silver ions dissolved in the electrolyte are electrolytically deposited on the cathode to form 99.99% metal silver.

Features

1. It can be quickly refined to obtain 99.99% metallic silver

2. Replace the traditional method of refining silver with nitric acid and it can reduce the consumption and emission of nitric acid.

3. The machine is easy to install.

4. The machine is simple to operate and maintain.

5. The machine adopts full anti-corrosion design and has a long service life.

Technical data

Using Instructions

1.Check whether each screw position of the machine is tightened, whether the titanium basket bag is damaged, and the water inlet valve and the water outlet valve are closed.

2.Strictly proportion water and nitric acid 100 : 10, Firstly prepare a potion with 10% dilute nitric acid.

3.Silver nuggets are evenly placed in 4 titanium baskets, and then poured into a 10% dilute nitric acid solution. the solution must be higher than the silver bar soaked surface.

4.Turn on the power switch, the adjustable voltage CV of the device is in the range of 5V-8V. The current is changed with the increase of the voltage,no need be adjusted. Click the electrolytic stirring switch device to operate normally.

5.The number of times to change the potion: it is based on the purity of silver, for example, the silver potion with low silver content and high impurity content, the potion needs to be replaced once for each refining, For example, if the silver content is high and the silver block with few impurities, the potion can be reused several times, and the number of changes depends on the cleanness of the potion.  

Design details

Electrolyzer

The surrounding titanium basket is used as cathode and the rotating titanium cylinder is used as anode, And the machine adopts full anti-corrosion design and has a long service life.

PLC control panel

The PLC electronic control system adopts a fully anti-corrosion design, and It is not easily damaged by chemical corrosion. it is easy to operate and does not require special personnel to supervise.

Titanium cylinder anode

The 99.9% and 99.99% pure silver obtained after electrolytic refining will be adsorbed on the cathode cylinder.

Exhaust fan

Help the machine to dissipate heat normally to ensure long-term continuous normal operation of the machine
