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.
