Shandong Yantai Mining Machine , Gold Electrowinning and Desorption Device
Product Description
Gold Electrowinning —Introduction
Desorption electrolysis system is applied to recover solid gold from carbons in the cyaniding process. It is equipped with liquid-level controlling system, temperature controlling system and automatic controlling system.

Product Feature
Gold Electrowinning — Features
High-efficiency: when the grade of loaded carbon reaches 3000g/t, the desorption rate can reach more than 96%, the barren carbon tenor with this equipment comparing 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°C(generally 30-55°C higher than in other kind system), and the working pressure of system can reach as high as 0.5 Mpa (generally 0.2-0.5 Mpa higher than in other kind system), so the desorption electrowinning is rapid with 12 hours typically(50%-60 % time shorted).
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.

Application
Gold Electrowinning — Application
Desorption electrolysis system is applied to recover solid gold from carbons in the cyaniding process.
Work Principle
Gold Electrowinning — Working principle
When the desorption system is added with anions which are more easily absorbed by activated carbons, Au(CN)2 is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.
