Product Description

Desorption electrolysis system

[Introduction] A complete set of system is applied to the treatment of gold-bearing charcoal in the coal pulp plant of gold mines, so that gold can be separated from the gold-bearing charcoal and precipitated into high-grade gold sludge.

[Gold Carbon Content] Over 3.5kg/t

[Application] It is used to extract solid gold from gold-bearing carbon by cyanidation.

[Improvement] The desorption electrolysis system consists of desorption column, electrolyzer, electric heater, desorption liquid tank, filter, electronic control cabinet, rectifier cabinet, circulating pump, activated carbon regeneration kiln, etc.

Advantages

1. The desorption electrolysis cycle is short.
2. The desorption rate is high. The desorption rate can reach more than 98% under the conditions of temperature 150ºCand pressure 0.5 MPa.
3. There is no need for sodium cyanide in desorption solution, no toxic and flammable components, and the cost of analysis is low.
4. The whole working process is in a closed pressure system, safe and reliable operation, no stimulating gas escaping from the workshop, good working conditions, low labor intensity.
5. The operating conditions of the system are strictly controlled, the technical indexes of production are stable, the quality of gold mud is high, and it is easy to extract without requiring back electrolysis.
6. After desorption and electrolysis, the gold content in lean liquor is generally lower than 2.5g/m³, the gold content in desorbed carbon is generally lower than 100g/t, and the quality of gold slime is high.
7. It is economically reasonable, technologically advanced and has broad prospects for development. It has been widely used in gold metallurgical industry.

Structure

The desorption electrolysis system adds anions easily adsorbed by activated carbon to the desorption system, thus replacing Au(CN)2-to realize gold desorption. The precious liquid obtained by desorption of gold-loaded carbon is recovered by ionization method to obtain solid gold.

The desorption electrolysis device is mainly composed of desorption and electrolysis. The process of desorption and electrolysis is separated so that the solvent is carried out in a comprehensive desorption tower. The noble liquid electrolysis is completed in an independent electrolytic cell. The four processes of solvent desorption, noble liquid heating, solvent condensation and solvent recovery are centralized in a comprehensive desorption tower, and the noble liquid obtained by solvent vapor desorption of gold-loaded carbon is concentrated. The crude gold is obtained by electrolysis in a separate electrolytic cell through a pipeline, and then the finished gold is purified.
