Desorption Electrolysis System

Desorption Electrolysis System

Product Introduction

Desorption electrolysis system obtains gold mud from carbon by desorption and electrowinning

Gold Loaded Carbon Content

≥3.5kg/t

Product Structure

Desorption electrolysis system consists of electrolysis equipment including desorption column and the electrodeposition tank

Advantages

  • In the high temperature (150℃) and pressure (0.5MPa), the desorption rate reaches 98%
  • Since desorption and electrolysis does not require different temperatures, it is not necessary to change temperature. The quickness and efficiency of machine dramatically diminishes gross electricity consumption by 1/2-1/4.
  • Desorption does not require sodium cyanide, which reduces cost and averts pollution.

Work Principle

In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au(CN)2ˉ 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.

Relative Equipment

The analytical column, electrolytic tank, filter, heater, analytical solution agitation tank, control electric wheel, DC power supply, measuring instrument
