Rapid Desorption Electrowinning

Our gold desorption and electrowinning equipment features high temperature, high pressure, no-cyanide, auto-control of desorption with features of high efficiency, low consumption and rapid.

High-efficiency: when the grade of loaded carbon reaches 3000 g/t, the desorption rate can reach more than 96%, the barren carbon tenor with this equipment compared with that of normal desorption electrowinning equipment will reduce to its one/fourth.

Rapid: The temperature of desorption electrowinning can reach as high as 150℃ (generally 30~55℃ higher than in another kind system) and the working pressure of system can reach as high as 0.5Mpa(generally 0.2~0.5Mpa higher than in another kind system) so the desorption electrowinning is rapid with 12 hours typically (50%~60% time shortened).


Low consumption: the same temperature for desorption, no need of heat-exchanging, working speed is rapid, power consumption is 1/2~1/4 of normal system.

No cyanide: no need of adding NaCH into the desorption liquid; low cost; no pollution.

High grade gold mud no need of anti electrowinning, gold slurry extraction easy.

Auto-control: the level-control system, temp-control system and autocontrol system set specially.

Safety: with 3 procedures of safety production, the system itself intelligent, auto-limiting pressure and pressure releasing unit, safety valve.
