Product Description

Gold Extraction Mineral Processing Cyanidation CIL Plant with Flowchart

HZE has made a number of projects of gold CIP (carbon in pulp) / CIL (carbon in leaching) solutions in the world and used unique advanced technology leaching tanks to improve gold recovery and reduce the consumption of chemicals and power. HZE has become a leader in gold processing industries with rich experience, exquisite technology and advanced processing.



HZE will conduct feasibility studies based on the condition of the raw ore, the metallurgical test report, the customer's mineral reserves and investment scale, and the conditions for building the plant, then propose a complete set of solutions for the plant which includes engineering design, equipment manufacturing and supply, Logistics, installation, commissioning, training, trial production and so on to ensure advanced technology, perfect processing, efficient plant construction, reduced investment, environmental protection and maximum benefits.
The gold ore sent to the processing plant will be crushed, screened, and ground to obtain the appropriate particle fineness. The wood chips and fibers in the slurry are removed, then the density of the slurry is usually increased by the thickener followed by cyanide leaching.
In the case of CIP processing, the slurry is leached by cyanide or other chemicals in several leaching tanks, and then the slurry enters the adsorption tank loaded with activated carbon to recover the gold in the solution. In the case of CIL processing, leaching and adsorption are carried out simultaneously in a number of tanks. Now CIL processing is more widely used.
The activated carbon loaded gold is periodically lifted and separated from the adsorption tanks,  then it is sent to the elution workshop after washing the mud and other impurities sticking on the surface of the carbon particles. HZE uses the advanced elution-electrowinning system with high-efficiency, energy-saving, high temperature and high pressure to produce gold mud. Each cycle of operation of this system takes only 10 hours to complete.



The gold mud is smelted to cast gold ingots after a series of processing: pickling, separating other metals, washing, filtering, drying, etc. The purity of the merging gold ingot can reach over 97%. If purification is required, further processing is required.
HZE strongly recommend that the tailings after leaching and adsorption are dewatered by the filters for the filtrate is returned back to the production water pond for recycling in the plant. The residual cyanide or other chemicals are reused, the consumption of the chemicals is reduced and the environment is protected, and the hazardous chemicals are prevented from being discharged outside the plant. After dewatering, the tailings are transported outside of the plant for storage.




1. What is the main business scope of your company?
HZE is a company with R&D center, design institute, manufacturing factories, installation and commissioning teams. Our customers are in the mining and mineral processing fields. Our major businesses include mineral processing EPC (engineering, procurement and construction), project consultation, engineering design, mineral processing equipment manufacturing, on-site installation, commissioning, staff training, customer project operation management, spare parts supply and technical support. Customers are free to choose any one or any combination of our services.


2. What are the outstanding advantages of your company?
The one-stop service of mineral processing engineering project and equipment is our core competitiveness.
The most important feature that HZE distinguishes itself from other engineering companies, design companies or consulting companies is that we are also an equipment manufacturer with a production plant of 50,000 square meters, and we have complete manufacturing rout and the related equipment.
HZE distinguishes itself from other equipment manufacturers by owning its own R&D center and engineering design institute.
HZE distinguishes itself from many mining machinery enterprises by possessing an expert team with members including not only senior engineers of the company, but also top Chinese technical experts, university professors and researchers.



3. What are the characteristics of your company's 3D design?
HZE not only uses 3D software to design equipment, but also uses 3D software to design process flow, pipeline, steel structure, auxiliary facilities, etc. of the whole mineral processing project. We even use 3D design for equipment packaging, container packing and equipment instructions manual. This greatly improves the quality of equipment and engineering, shortens the construction period, facilitates technical discussion and evaluation, facilitates project management, improves construction safety and reduces project cost.

4.  What are the service features of your company?

1. Customers who whether buy our equipment, or entrust us with EPC, or require us to provide a certain service, cooperate closely with us to carry out specific operations and supervise our implementation throughout the process.
2. HZE will try to understand the basic situation and needs of customers as detailed as possible before the sale, formulate a preliminary plan according to the specific situation of customers, and get unanimous opinions after communications and discussions with customers to determine the plan.
3. We set up customer files for every customer who signed the contract with us and upload them to the Cloud where customers can also get an account and password. Customers can have all the documents, videos and pictures, technology, services, execution, operation, management and control, maintenance and so on related to the business.
4. Whether it is in the process of general contracting, equipment manufacturing or providing some kind of service, we welcome customers to know about our implementation on the spot or through the network, and put forward requirements and opinions.
5. We assist users who have used our products to formulate operation specifications and make suggestions on maintenance plans and spare parts inventories. In addition to routine on-site installation, commissioning and training, during the production period after we handing over equipment to customers for use, we often understand the equipment using situations through the network and provide guidance and training to customer management and operators.
6. For the clients who have just start the mining business, we provide the opportunity of training and practice in China's mines for the clients' employees, until they are skilled in operation and maintenance.
