Our advantages:
1. High efficiency: in crushing, it adopts traditional two-stage and a closed circuit system for ideal fineness. Besides, jaw crushers have large crushing capacity.
2. Saving energy in grinding and classification, with characteristics of large processing capacity and small floor area, superfine lamination autogenous mill can save energy by more than 85%.
3. Good classifying effects :in classification, hydrocyclone and vibrating screen can enhance the classifying effects.
4. Environmental protection :i t adopts the third generation tailings dry stacking technology, which can save energy by 60-80%. Furthermore, it can also protect the environment and build a base for green mine.
Production technology:
Raw material ores is exploited from mountain are big size, so it is necessary to crush firstly, in this process, the raw materials will be feed into primary crusher by feeder, then come into secondary crusher.The materials will go into screen after first and secondary crusher, the suitable size material (â?¤25mm) will go to next step. Oversize(ï¼?25mm) material will go back to secondary crusher to crush again. This forms a closed crush circuit.
In this process, material will be grinded into suitable sizes (about 200 mesh) for beneficiation.After grinding material will come to classifier. In classifier, suitable size material will go to next step. Coarse material will go back to ball mill for grind again. This process is a closed grind circuit.
In this process, materials will be separated by flotation, magnetic separator or gravity concentrating machine. We will get the materials that we need.
Process introduction: after beneficiation, there are some residual water in ore concentration. So we have to carry on concentrate dehydration to meet the requirements of transportation and smelting.
The mian method of molybdenum ore beneficiation is flotation. The recovery molybdenum is molybdenite. Sometimes in order to improve quality of molybdenum concentrate and to remove impurities, molybdenum concentrate is dealt by chemical beneficiation once again. Molybdenite crystals has six-layered or plate-type structure which is formed by paradigm of health along the inter-layer s-mo-s structure and the layer of polar covalent bond s-mo. The binding among layers is weak, but covalent bond binding inner the layer is strong. So molybdenite is easy solution fissure along structural layer to show sheet or plate. This is the reason that digenite has well floatability in nature. Practice has proved that with suitable grinding fineness, molybdenite crystals dissociat in s-mo-s layer and the hydrophilic s-mo takes up little area. But through mill, the area ratio increases, and floatability reduces. Although at this time to add some quantity of polarity collector such as xanthate, which is benefit for the recovery of molybdenite, new slime, caused during mill, affects flotation results. So molybdenite of sorting should avoid and prevent grinding. In the production, we should take the process of sub-ore grinding and multi-stage sorting to achieve monomer dissociation and to make sure high recovery rate of molybdenum.

1. The gold centrifugal concentrator is a relatively new type of gravity concentration equipment.The machines utilizes the principles of centrifugal to enhance the gravitational force experienced by feed particles to effect seperation based on particle density. 2.The key components of the unit are a cone shaped concentrate bowl, rotated at high speed by an electric motor and a pressurize water jacket encompassing the bowl. 3.Centrifugal concentrator can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation and recover gold from the old tailings. 4.Application shows that the recovery can be as high as 99precentage and the concentrating ratio is up to 1000times.In recovering the natural gold in lode ore with 65percentage of the ore having a milling size -0.074mm, the recovery for the natural gold is up to 98percentage.For the natural gold of 0.004mm in particla size, the gold recovery is 97percentage.The equipment is patented in china.
Beneficiation spiral chute integrates features of spiral concentrator, shaking table, and centrifugal separator. It the best equipment for mineral processing, especially used for mining sands in coastal, river, sand beach, river road, etc. Beneficiation spiral chute is adapted to process alluvial deposit, especially flat materials with high monomer dissociation degree of useful minerals. Besides, since minerals containing high mud have low concentrate quality, so they must be de-slimed and graded before entering into the beneficiation spiral chute. The working features of beneficiation spiral chute is that the concentrate, middling and tailings are gotten at the end of the equipment, and the sorting process does not need washing water. Spiral chute is the main component of the device, which is made of polyurethane wear-resistant plastic or mixed artificial corundum resin. Its liner is made of FRP a wear-resistant material. On the top end of beneficiation spiral chute, there is a mineral separation device and a feed tray; at the lower part of beneficiation spiral chute, there is a products interceptor and a trough for receiving ores. The whole equipment by pioneers manufacturer stands vertically though still frame.
