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. It consists of electrolysis equipment including desorption column and the electrodeposition tank.
SCOPE OF APPLICATION:
It is used to extract solid gold from gold-bearing carbon by cyanidation.
Product Description
In the Desorption electrolysis system, anions that are easily adsorbed by activated carbon are added to the elution system to replace Au (CN)2-and desorb gold. After loaded carbon elution process, the solid gold is recovered from pregnant liquid by ionization method.
The high-efficiency, low-consumption elution and electrowinning device is mainly composed of two parts: elution and electrowinning, and the processes of them are separated. The solvent desorption is in elution column, and the precious liquid electrolysis is completed in a separate electrolytic cell. The four processes of elution, pregnant liquid heating, solvent condensation and solvent recovery are concentrated in the elution column. The pregnant liquid after desorbing the gold-loaded carbon by the solvent vapor is introduced into a separate electrolysis through a pipeline tor electrolysis to obtain crude gold, which then purified to get product gold.
