Product Description

Raw Ore Mineral Processing Gold Mining Equipment

Gold Processing Plant
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.
HZE has extensive experience to recover gold, silver and other valuable metals by flotation, gravity, leaching and other processing to provide comprehensive services to large, medium and small-scale gold processing plants.


Gravity Concentration
If the gold ore has much granular gold (free gold) which can be to recovered by gravity to get a good benefit.
The ore is the grinding circuit after the stage of crushing and screening. If the raw ore contains some sticky slime and clay, the washing equipment such as the trammel screen or scrubber should be added into the crushing circuit.
Commonly used gravity equipment includes jigs, centrifugal concentrators and shaking tables. The sluice boxes are also used as effective facilities for efficient gold recovery.
The concentrate obtained by gravity can be produced the ingots by pyrometallurgy or hydrometallurgy.
The tailings of gravity can be pumped to the tailings impoundment or sent to the circuit of flotation, cyanidation or others to recover the residual gold as much as possible.

 

Froth Flotation
The gold ore sent to the processing plant will be crushed, screened, and ground, then the slurry enters the flotation stage generally. Flotation acts to sulfides and free gold normally, and it is necessary to use appropriate chemicals for slurry mixing and gold recovery by flotation. Generally the flotation circuit includes rougher, scavenger and cleaner to obtain a satisfactory concentrate.
If the ore contains some free gold particles, gravity separation equipment is generally added to the grinding circuit to recover the particulate gold.
If the ore contains much oxides, some gold is difficult to recovered by flotation. It is possible to combine flotation and cyanidation to increase recovery.


Cyanide Leaching
Generally sodium cyanide is used for leaching gold from ground raw ore or re- ground concentrate to obtain pregnant solution. Gold in pregnant solution is adsorbed by activated carbon or precipitated by zinc.
Usually heap leach or vat leach extracts gold from low grade ore. Raw ore is leached on pad to get pregnant solution after crushing and agglomerating. Activated carbon absorbs gold out of pregnant solution.
Gold loaded carbon is processed by stripping and electrowinning to get gold slime. Pregnant solution is precipitated by zinc to produce gold slime.
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

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.
