Working Principle
Add some anion more easily absorbed by activated carbon to replace Au(CN)2- and realize the desorption of gold. The pregnant solution from desorption of gold loaded carbon will be recycled by the ionizaion method, so as to get the solid gold.
Product Advantage
* High temperature, high pressure, cyanide-free, desorption automatic control, high efficiency, low energy consumption, and fast operation.
A. High efficiency: When the grade of the gold loaded carbon reaches 3000g/t, the desorption rate can reach above 96%. The grade of barren carbon can be reduced by 3-4 times than that of the conventional desorption electrolysis device.
B. Rapid: The temperature of the desorption electrolysis can reach 150ºC (30-55ºC higher than that of other models at the first stage), and the working pressure of the system can reach 0.5MPa (0.2-0.5MPa higher than that of other models at the first stage). Therefore, the time for desorption electrolysis is very soon, which is generally 12 hours, with nearly 3 times shortened.
C. Low consumption: The temperature of desorption electrolysis is the same with no need to heat. As the operation is fast, the total power consumption is 1/2-1/4 of the conventional system.
* Cyanide-free: No sodium cyanide is added for desorption electrolysis to realize low costs and no pollution.
* High grade of all slime without anti electrolysis with easy extraction of gold mud
* Automatic control: Specially set liquid level control system, temperature control system and automatic control system.
* Safe: With triple safety protection measures, namely, self intelligent system, automatic pressure limiting and release system and safety valve.
Application
It is used for the extraction of solid gold from gold loaded carbon by cyanidation.
