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.
Process: Leaching Pulp Preparation Cyaniding Leaching and Carbon Adsorption Gold Loaded Carbon Desorption Pregnant Solution Electrodeposit Carbon Acid Regeneration Leaching Pulp
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).
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.
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.
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.
"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 ISO9001:2015quality management system certification, Xinhai is classified as the assured brand with advanced products and standard quality!
Xinhai currently has many patents technologies, the extraction of gold plants spread among China, Southeast Asia, South America, Africa, Russia, Mongolia, North Korea and other places, and Xinhai has established offices around the world.
Flotation process is a mineral separation method that according to the hydrophobicity differences of particle surface. Copper sulfide is the main mineral of copper concentrates, which possess good inherent floatability, so it is usually separated by flotation method after crushing and grinding. Copper flotation operation is usually carried out in flotation cells or flotation columns. After air inflation and agitation, the useful minerals are adsorbed on the bubble surface. Therefore, high efficient and stable flotation equipment is the basic guarantee for the smooth flotation operation.
Xinhai is a professional mineral processing equipment manufacturer in China, and it has completed more than 500 mineral processing EPC projects. Besides, Xinhai pays great attention to its product improvement according to a large number of mine design cases. Aiming at copper flotation equipment, Xinhai has optimized and improved a high-efficient and energy-saving circular flotation cell on the basis of traditional flotation cell, which can be widely used in various metals and non-metallic minerals. The circular channel is convenient for site construction, saves occupied area and reduces investment. At the same time, the force distribution of the circular flotation cell is relatively even and easy to realize the large-scale equipment. What's more, the circular flotation cell has a very good flow mechanics feature, without dead angle and settlement. The shape of impeller and the flow mechanics feature of flotation cell can reduce the power consumption, save more 15% ~ 20% compared with the same type of flotation equipment. Because reagents mix well with minerals, the foam is rich and stable, the recovery index of this flotation cell is 50% ~ 20% higher than that of same type flotation cell.
Xinhai is a professional mineral processing equipment manufacturer in China, who possess a large number of mineral processing EPC project experience and professional research team. If you want to learn more details, please contact us.
