Xinhai: Application Example of High Efficiency Desorption Electrolysis System

01Desorption Electrolysis System Introduction

Mainly used for gold loaded carbon of gold CIL, Xinhai high efficiency desorption electrolysis system CIL technology process can separate gold from  gold loaded carbon then desposited into gold mud, characterized by high  efficiency and quickly, lower energy consumption, this mineral processing  method is an essential system for producing finished gold.

02Features Of Desorption Electrolysis System

Characterized by high efficiency and quickly, lower energy  consumption, this auto control with  high  temperature, high pressure and oxygen free desorption electrolysis CIL system  has safety facilities, advanced technology index, as well as features like easy  to control and stable operation.

1. High efficiency

Poor carbon keeps low in grade, 96%  desorption rate can be get when gold loaded grade reaches 3000g/t.

Poor carbon grade can lower 3 - 4 times  than the common system, which can beneficial  to improve adsorption rate of drain rate, what’s more, it also lower gold loss  of cyanide tailings, which can improve practical recovery rate.

2.Quick

Xinhai desorption electrolysis system can reach 150℃,  0.5Mpa, which is higher 0.2-0.5MPa of ordinary one, lower almost 3 times than  ordinary system operation time, and can finish desorption with 12-14 h.

3. Lower energy consumption

Saving 1/2 to 1/4 power than  common system.

4. Oxygen free

Without sodium added in desorption liquid, Xinhai high  efficiency desorption electrolysis system featured by low cost and zero  pollution.

This system can provide negative materials due to customers request,  gold mud also has higher grade than the ordinary one, which don not need  anti-elcctrolysis, and easy to extract as well as saving cost.

5. The automatic control level buffering mechanism

On account of liquid gasification and the changes of system  pressure when system operating, level buffering mechanism produced, which can automatically  counteract the level changes and keep stable liquid level.

Temperature control system: when temperature reaches the set  value, the system can cut some of the electric heaters, leave other electric  heaters operating normally. Otherwise, the cut electric heaters will be put  into operation to keep the system temperature running in a stable set value.

6. Triple safety measures

First of all, automatically intelligent system. If  circulating pump is not running, liquid will not flow, in case of local  steaming and pressure rise, the electric heater will stop working as well, this  happens to blockage too. Meanwhile, when circulating pump start to work  properly, or pressure slow down, electric heater will put into operation  automatically.

Secondly, specialized pressure release system has been  installed. When system pressure is over high, this system will release pressure  automatically until to the normal value.

Thirdly, safely valve has been installed. Only when the  above measures jointly out of work that runs the safely valve.

03System Structure of Desorption Electrolysis System

Xinhai high efficiency desorption electrolysis system mainly  composed of desorption part, electrolysis part, instrument control section, and  pipe valve, etc. each part deeply interpenetrated with each other to form a  complete system.

04Cases of Desorption Electrolysis System

1. Busolwa 1200tpd Gold Mine Project, Tanzania

Desorption electrolysis system is an essential part of the  all slime cyaniding CIL technology process. Desorption electrolysis is a set of  system, the following is a panorama of desorption electrolysis system of the  factory. >>>View more

2. Iron Cap 700tpd Gold Mine Project, Zimbabwe

This is electrolysis system of finished installation. Leaching  system absorbs gold loaded carbon, then put them into high temperature and  pressure electrolysis system to extract gold. alloy gold can be get after  smelting the gold mud in high efficiency melting furnace.
