Desorption Electrolysis System

[Introduction]: Desorption electrolysis system as gold extraction equipment obtains gold mud from carbon by desorption and electrowinning

[Capacity]: ≥3.5kg/t

[Improvement]: Desorption electrolysis system consists of electrolysis equipment including desorption column and the electrodeposition tank

Desorption-Electrolysis-System

ADVANTAGES

In the high temperature (150℃) and pressure (0.5MPa), the desorption rate reaches 98%;

Since desorption and electrolysis does not require different temperatures, it is not necessary to change temperature;

The quickness and efficiency of machine dramatically diminishes gross electricity consumption by 1/2-1/4;

Desorption does not require sodium cyanide, which reduces cost and averts pollution.

PRODUCT STRUCTURE

Separation-Drawing-of-High-Efficiency

In gold electrowinning process,when the electrolysis equipment is added with anions that are more easily absorbed by activated carbons, Au(CN)2ˉ is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution processes the via ionization. At last, the solid gold is attained.
