Product name: Desorption Electrolysis System,Desorption electrolysis equipment complex,Desorption and Electrowinning System
Handling capacity: ≥3.5kg/t
Application: used for cyanidation to extract gold from gold-loaded carbon to extract fixed gold
Structure: An output shaft of the motor is connected to the outer magnetic cylinder, thereby forming a sealed whole between the pump and motor. The inner magnetic cylinder has an impeller attached to one end, the outer magnetic cylinder and the motor run synchronously, under the action of centrifugal force, the medium can circulate.
1. High temperature and high pressure type:
Gold ore beneficiation equipment used for high-temperature and high-pressure desorption and electro-accumulation of gold-loaded carbon in order to extract gold mud; cyanidation is used to extract solid gold from the gold-loaded carbon.
Desorption electrolysis at high temperatures and pressures, process model Y13-150/200/250, desorption electrolysis temperature 150 °C, pressure 0.60MPa, desorption agent sodium hydroxide, working time 8-16 hours.
Under the conditions of high temperature (150℃) and high pressure (0.6MPA), the desorption rate reaches more than 98%.
③ Rapid desorption electrolysis system (about 12hrs).
2. Standard temperature and pressure type:
In cyanidation, gold is extracted from gold-loaded carbon by desorption and electrowinning at standard temperatures and pressure. A set of gold beneficiation equipment is used to remove gold mud from gold-loaded carbon by desorption and electrowinning.
Desorption electrolysis, normal temperature and normal pressure, CC13-150/200/250, desorption and electrolysis temperature 90-95 °C, normal pressure, desorbent sodium hydroxide and sodium cyanide working time 48-72 hours.
①Compared with high temperature and high pressure, the work efficiency is lower;
②More consumption items are required;
③About 40 hours/time desorption electrolysis system.
To analyze the electrolysis system, we add activated carbon that adsorbs anions readily in the desorption system, so that AU(CN)2- is replaced to achieve gold desorption. Ionization is used to recover solid gold from the precious liquid obtained by desorption of gold-loaded carbon.
Electrolysis and desorption are the main parts of the process. Electrolysis of the precious liquid takes place in an electrolytic cell, while the desorption of the solvent takes place in a desorption tower. As a result of the desorption of solvent vapor after carbon, the precious liquid obtained is electrolyzed in a separate electrolyzer through a pipeline to yield crude gold, which is then purified to yield finished gold.
