Desorption electrolysis system process

In gold electrowinning process, when the electrolysis equipment 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, the pregnant solution is processed via ionization. At last, solid gold is attained.

In the high temperature (150℃) and pressure (0.5MPa), the desorption rate reaches 98%. Since desorption and electrolysis do not require different temperatures, it is not necessary to change temperature. The quickness and efficiency of the machine dramatically diminish gross electricity consumption by 1/2-1/4. Desorption does not require sodium cyanide, which reduces cost and averts pollution. In gold electrowinning process, when the electrolysis equipment 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, the pregnant solution is processed via ionization. At last, solid gold is attained.
