Xinhai Gold CIL Process Description：
Leaching Pulp Preparation
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).
- 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.
Cyaniding Leaching and Carbon Adsorption
Xinhai specialcoconut shell activated carbon
Xinhai special coconut shell activated carbon is featured with small hole, high reaction activity, wear-resistance and renewability, the adsorption speed increases 30%.
- Xinhai special coconut shell activated carbon greatly improves golf recovery 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;
Carbon Acid Regeneration
- Ensures the minimum carbon gold loses during transmission, it lower the gold loses and the processing line is easy to maintain.
Pulp Agitation
- 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.
Gold Loaded Carbon Desorption
- 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.

Xinhai CIL Gold Process Flowchart
Cases
In January 2015, Xinhai undertook Tanzania 1200tpd gold project 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.
In March 2015, Xinhai took charge of African Zimbabwe Huangzhi 700tpd gold project, 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 recovery 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 Processing 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 gold processing plant, Since its establishment 20 years, Xinhai has been committed to gold processing service the development and innovation of equipment, and has formed the complete gold processing 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 gold processing plant industry.
EU Certification International Quality
"Create a global brand, based on global gold markets " has been one of the strategic thought of Xinhai, depending on its professional gold processing service, Xinhai has got the EU certification, and ISO9001:2008 quality management system certification as early as in 2008, Xinhai is classified as the assured brand with advanced products and standard quality!
112 patents technologies, more than 500 mineral processing plants in the world
Xinhai currently has 112 patents technologies, the gold dressing plant projects spread among China, Southeast Asia, South America, Africa, Iran, Russia, Mongolia, North Korea and other places, and Xinhai has established offices around the world.
