XINHAI CIL GOLD PROCESSSING

XINHAI CIL GOLD PROCESSSING

Simple Process, Easy to Operate, Save Construction Investment 20%, Fast Absorption Rates, High Recovery Rate

Since its establishment 20 years, Xinhai has been committed to the Research and development of extraction of gold, including gold extraction technology and equipment, after the constant study of Xinhai research technicians, Xinhai has formed a set of efficient, environmental, energy-saving and economic Xinhai CIL gold processing.

【Application】: Mainly applies for the extraction of gold that the ore has above 1g/t grade gold ore and gold ore with large bearing ore volume: silver, platinum, copper, etc.

Recommend Xinhai gold flotation process for small gold plant.

Xinhai CIL Gold Processing Description：

1.

Leaching Pulp Preparation

Equipment：

Xinhai Efficient Leaching Agitation Tank

Flow：

Add the gold ore slurry into 9 leaching agitation tanks, pour in cyanide solution in first 2 tanks, activate carbon in the following 7 tanks for the reverse-absorption process (the number of tanks depend on the capacity size).

Advantages of leaching pulp in Xinhai CIL gold processing:

  • Greatly reduce the number of leaching tank;
  • Shorten the time of gold staying in the cyanide pregnant solution;
  • Reduce the capital backlog in gold staying process, get gold quickly, fast capital return.

3.

Carbon Acid Regeneration

Equipment：

Xinhai Hydraulic Filter Press, High Frequency Dewatering Screen

Advantages of carbon acid regeneration in Xinhai CIL gold processing:

  • Ensures the minimum carbon gold loses during transmission, it lower the gold loses and the processing line is easy to maintain.

5.

Gold Loaded Carbon Desorption

Equipment：

Xinhai Desorption Electrolysis System

Advantages of desorption electrolysis system in Xinhai CIL gold processing:

  • Adopts Xinhai high-temperature and high-pressure desorption (150℃，0.5Mpa), which can desorb 99% gold within 2-6 hours;
  • Pregnant solution contains high concentrations of gold and silver Cyanide complex ions, and less impurity ions, after the process of Xinhai efficient, low-powered and fast desorption electrolysis system, high purity solid gold can be obtained safely and economically.

Cyaniding Leaching and Carbon Adsorption

Equipment：

Washing Thickener

Material:

Xinhai special coconut shell activated carbon

Material feature:

Xinhai special coconut shell activated carbon is featured with small hole, high reaction activity, wear-resistance and renewability, the adsorption speed increases 30%.

Advantages of carbon adsorption in Xinhai CIL gold processing:

  • Xinhai special coconut shell activated carbon greatly improves the extraction of gold from associated metal, significantly improves the economic benefit and production efficiency;
  • Xinhai washing thickener adopts continuous discharging, which reduces multiple cycles of hydrothermal gold, recycle early; extends the time of pulp concentration, increases the leaching rate;
  • Xinhai washing thickener achieves countercurrent washing, which has large volume and high washing efficiency;

4.

Pulp Agitation

Equipment：

Xinhai Central Air Lifter

Advantages of pulp agitation in Xinhai CIL gold processing:

  • Convey pulp fast, making pulp in small cycles;
  • Reduce power consumption 70%;
  • Solid materials suspend evenly;
  • Activated carbon with low wear;
  • High gold recovery rate.

Cases

Tanzania 1200tpd Gold Project

In January 2015, Xinhai undertook Tanzania 1200tpd CIL gold processing plant of a mining company, the project adopted Xinhai gold CIL process, after construction design and installation, it has been put into production now, the recovery rate of gold production line reached expected goal, the final gold leaching rate was 91.5%, which brought large amount of economic benefits for clients and obtained high praise from clients.

Zimbabwe Huangzhi 700tpd Gold Project

In March 2015, Xinhai took charge of African Zimbabwe Huangzhi 700tpd CIL gold processing plant, the plant is mainly quartzite gold mine, most is oxidized ore or primary ore with low sulfur ore, so Xinhai chose gravity separation + all-sliming CIL process, which achieved efficient extraction of gold, save 15% cost. Equipment still operate smoothly after put into production one year, customer are very satisfied with this result.

Class B Design Qualification, 20 Years of Gold Extraction Experiences

Xinhai has make Class B design Qualification, set up mine design institute and mineral processing research institute, more than 200 professionals provide the technical support service for the extraction of gold, Since its establishment 20 years, Xinhai has been committed to the development and innovation of process and equipment used in the extraction of gold, and has formed the complete extraction of gold system. Xinhai concentrates on providing the Turnkey Solution for Mineral Processing Plant that is research and design- complete equipment manufacturing and procurement- commissioning and delivery”, striving for building the international leading enterprise in the extraction of gold.
