Gold Elution and Electrowinning Device

Product Description

Gold Elution and Electrowinning Device —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.

The 1500kg/batch electrowinning device in Zimbabwe

Product Feature

Gold Elution and Electrowinning Device —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 Elution and Electrowinning Device —Application

Desorption electrolysis system is applied to recover solid gold from carbons in the cyaniding process.

Work Principle

Gold Elution and Electrowinning Device —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.

Case

Kush Clients Consulting Mineral Processing

Clients of Kush project paid a special visit to Xinhai on Jan 18, 2014, for detailed communication with the Xinhai technicians. They made an estimate of the size , investment as well as earnings of the mill plant. During this meeting, based on rich experience of mineral processing and mill plant, Xinhai technicians wined the clients trusts for answering clients questions.

Kush Gold Mineral Processing Test

After the contract was signed, Clients posted to Xinhai two packages of samples, totally weight 400kg. Xinhai Mineral Processing Institute provided comprehensive mineral processing test after precious test.

The mineral processing test made an analysis to the gold content which is 4.31g/t, thus Xinhai technicians decided to recovery gold directly through the solution of CIP cyaniding, which including grinding the raw ore to 88.0% -200mush,and using lime as alkali, then adding sodium cyanide, agitating then leaching.The pulp density can reach 40%, 4kg/t of slime, 2kg/t sodium cyanide, the leaching rate of gold can get 91.45% which is perfectly good. While it was worth mentioning that the Institute noticed that if adding gravity separation, the recovery rate will not notably improved while increased the mineral processing cost. For the benefits of the customers, Xinhai technicians suggested cyaniding directly, while the customers firmly believed that with the deepen exploiting, the gold grade can increase to 8g/t, and considering finding large particles around the mine, technicians decided to adopt the solution of gravity separation + cyaniding the tailings after gravity separation.

Mine Design

Mine design, an vital part of Xinhai mineral processing EPC, was in charge of Xinhai Mining Design Institute with Class A Certification. For better suiting the actual situation of the project, technicians of the Mining Design Institute made field survey to the surroundings such as terrains, waters and power supply, then designed the construction drawing elaborately and gave 3D simulation based on the processing flowchart and the equipment selection mine processing test provided.

Installation & Commissioning

After the Equipment manufacturing and purchasing, the perfect packaging and delivery system can guarantee the security service.

Xinhai Installation & Commissioning Operation Center Project No.1 was in charge of as well as full participation the field installation & commissioning. On the one hand, they supervised the construction site to inspect any problems, on the other hand , they optimized the production and management process to improve interests for customers.
