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.

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.

Features of jaw crusher
1)high crushing ratio.
2)even product granularity.
3)simple structure.
4)wide ranges of choice.
5)convenient maintenance.

Working principle of jaw crusher:
The motor transmits power through belt, drives the moving jaw to do periodic motion towards the fixed jaw by the eccentric shaft.The angle between toggle plate and moving jaw plate increases when moving jaw moves.So the moving jaw moves towards the fixed jaw.The stuff will be crushed in this process.The angle between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.

1. Brief introduction of cone crusher, symons crusher
Cone crusher is generally used as a secondary crusher in a crushing circuit.Pre-crushed product (usually 3in minus depending on the cone crusher model) is fed through the top of the cone crusher and flows over the mantle.The vertical cone crusher drive shaft rotates the mantle eccentrically below the concave, or bowl liner, squeezing the product and
