Description
Desorption electrolysis equipment is used in cyanide alchemy to extract solid gold from gold-loaded carbon. The principle is as follows: Anions that are easily adsorbed by activated carbon are added to the desorption system, thereby displacing Au(CN)2- and achieving the desorption of gold. The precious liquid obtained by desorbing gold-loaded carbon is recovered by ionization, thereby obtaining solid gold.
Advantages
Cyanide-free
No sodium cyanide needs to be added to the desorption liquid, which is low-cost and causes less pollution. The gold slime has a high grade, does not require reverse electrolysis, and is easy to extract.
Automatic control
A special liquid level control system, temperature control system and automatic control system have been set up.
Safety
It features triple safety protection measures, namely, the system’s own intelligence, an automatic pressure-limiting force release mechanism, and a safety valve.
Working principle
In the desorption system, anions that are easily adsorbed by activated carbon are added to displace Au(CN)2-, thereby achieving the desorption of gold. The precious liquid obtained by desorbing gold-loaded carbon is recovered by ionization, thereby obtaining solid gold.
