Desorptionand electrowinning system

Product Introduction

Desorptionelectrolysis system obtains gold mud from carbon by desorption andelectrowinning

GoldLoaded Carbon Content

≥3.5kg/t

ProductStructure

Desorptionelectrolysis system consists of electrolysis equipment including desorptioncolumn and the electrodeposition tank

Advantages

In the high temperature (150℃) and pressure (0.5MPa), the desorption rate reaches 98%

Sincedesorption and electrolysis does not require different temperatures, it is notnecessary to change temperature. The quickness and efficiency of machinedramatically diminishes gross electricity consumption by 1/2-1/4.

Desorptiondoes not require sodium cyanide, which reduces cost and averts pollution.

WorkPrinciple

In goldelectrowinning process,when the electrolysis equipment is added with anionswhich are more easily absorbed by activated carbons, Au(CN)2ˉ is replacedby anion and the gold desorption is achieved. After the carbons loaded withgold are desorbed, pregnant solution is process via ionization. At last, solidgold is attained.

RelativeEquipment

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