Normal temperature and normal pressure desorption electrolysis equipment is composed by electric heater, elution  column,heat  exchanger,electrolyzer,pump  and  etc.

Temperature of desorption  is  120±10℃,operation  pressure  0.2±0.1MPA,temperature  of electrolysis  is  90- 98℃,Processing time of Gold Loaded Carbon is 30-36 hours/batch,and also the desorption liquid need to add certain sodium cyanide.

The system employs a two-stage process: desorption and electrolysis.

Desorption: Activated carbon, with its affinity for anions, is introduced into the system to replace the Au(CN)2- complex, thereby desorbing gold. This process occurs in a desorption tower.

Electrolysis: The gold-laden solution from the desorption stage is transferred to an electrolytic cell. Here, ionization is utilized to recover solid gold. The crude gold produced undergoes further purification to yield finished gold.

In essence, the system involves desorbing gold from the carbon using a specific chemical environment and then recovering the gold through electrolysis.
