A system obtains gold mud from carbon by desorption and electro winning
Desorption electrolysis system consists of desorption column and the electrodeposition tank
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.
desorption system is added with anions which 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 is process via ionization. At last, solid gold is attained.
