Gold recovery bath with brightener - 500 ml

The bath is based on thiourea. It is produced from chemically pure reagents and distilled water. This makes it very stable in terms of operating parameters.
The gold recovery bath with brightener , in addition to thiourea and mineral acid, contains a brightening agent - antipyrine with other additives.

After the gold recovery bath, the processed object must be tumbled. If gold recovery is carried out well in a bath with a brightening agent, it is even possible to avoid tumbling and certainly to reduce its duration and intensity.

Each precious metal processing plant has its own specific operating conditions and equipment, which makes it necessary to select the operating parameters of the gold recovery bath individually. The general principles are as follows:

- voltage 6 - 12 V
- current density 1 - 5 A/dm² (for a 3g workpiece, current 1 A)
- electrodes made of stainless steel, platinum, graphite or copper
- temperature 80 - 95 ^oC (in case of water jacket heating, water in the jacket should boil)
- add a new batch of preparation as the bath is used up
- move the bath or the workpiece as much as possible
- use as large a surface area as possible for the electrodes (cathodes)
- make sure that the workpiece subject to gold recovery and the electrodes have good contact
- work under extraction ventilation - the fumes have an unpleasant smell

Dilute the contents to a volume of 1 litre with distilled or boiled water.

Once the above-mentioned conditions are fulfilled, adjust the bathing process: time of gold recovery, current density, voltage (in exceptional cases). We guarantee that, once properly selected, the working conditions will result in a great deal of satisfaction with the use of the gold retrieval bath.

Gold recovery

Some gold is deposited on the cathodes. It can be scraped off from time to time. The remaining gold in the form of a precipitate is at the bottom of the vessel. Gold recovery involves boiling the used bath for as long as possible (adding "normal" water from time to time) to drive off as many chemical compounds as possible from the bath. Then thermally decompose the residual compounds by burning and refining the recovered gold.

Bottle capacity: 500 ml.
