Desorption Electrolysis System

Product Introductio

Desorption electrolysis system obtains gold mud from carbon by desorption and electrowinning.

Gold Loaded Carbon Content

>=3.5kg/t.

Advantages

High grade gold mud, without anti-electrolysis, extraction easy.

Cyanide-free: desorption solution without cyanide, low cost, non-polluting.

At a high temperature (150 ℃), high pressure (0.5MPa) conditions, the desorption rate of more than 98%.

Desorption temperature electrolysis same, without heat, as a result of fast, power consumption is a regular system of 1/4 to 1/2.

Security: triple security measures, the system itself is intelligent, automatic pressure limiting pressure release mechanism, the insurance safety valve.

Desorption toxic combination of agents containing carbon activator, plays regeneration of carbon, carbon-lean regenerated without fire, saving the cost of carbon regeneration..

Work Principle

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, pregnant solution is process via ionization. At last, solid gold is attained.

Applications

Alchemy for cyanidation to extract gold from gold-bearing solid charcoal.

Relative Equipment

The analytical column, electrolytic tank, filter, heater, analytical solution agitation tank, control electric wheel, DC power supply, measuring instrument.
