How to use large flotation machine to separate copper and molybdenum ore

By -

 About 90% of non-ferrous metal recovery in the world will use flotation method, in order to realize mineral flotation flotation machine plays a great role. Large-scale flotation machine can significantly improve the processing capacity of beneficiation, reduce consumption, and obtain higher benefits.

The flotation machine is a motor that drives the rotating shaft to rotate the impeller. Under negative pressure, the pulp moves between the impeller and the stator, and the centrifugal blower is evenly dispersed in the air through a porous cylindrical air distributor for mineralization. After the stator is stabilized, it rises to form a stable foam layer, and enters the next operation through the upper foam tank. The remaining slurry will flow through the flow holes in the tank wall to the next tank for sorting, and finally become tailings.

flotation machine


The main characteristics of tooth decay of the super large flotation machine are:

(1) The pulp aeration and bubble mineralization effect is good.

The air coming in from the blower will directly enter the air inlet on the top of the flotation machine through the air duct. A regulating valve that controls the air volume is installed at the air inlet. The air can directly enter the hollow shaft to ensure that the slurry in the flotation machine is not fully affected by the equipment. Mineralization. And a good amount of aeration can effectively suspend the mineral particles in the entire flotation tank and evenly distribute the bubbles.

(2) Energy saving and loss of equipment.

Before the flotation machine, air was directly fed between the impeller and the stator by the blower. After the hollow shaft rotates, the equipment can make the air into the suspension state formed after stirring at low speed and enter the selection for selection. The stator adopts The form of low damping changes the direction of the slurry flow to the radial direction, which can reduce the resistance circulation and power consumption of the slurry.

(3) High efficiency of automatic liquid level control. The slurry level in the flotation machine can be detected by a slurry level gauge, which can realize automatic control of the slurry level. The tailings box and the middle box have a cone valve to control the flow of the slurry, which is controlled by a pneumatic actuator, so that it can be used for full adjustment of the slurry.

(4) Conducive to improving the selection effect. The deep cone structure can mineralize the pulp to provide a stable foam zone and a longer separation zone, so that low-pressure air can be fully dispersed in the solid, liquid, and gas three-phase strong turbulent mixing zone at the bottom of the flotation machine, which can generate bubbles If it is fully utilized, there is a large speed difference between the bubbles and the pulp. There are more opportunities for fine particles to contact the bubbles, and the fine particles will fully float out. The slurry will sink, increase the chance of collision of bubbles and increase the chance of flotation.

(5) Convenient operation and management of equipment.

Can drive the load to start; advanced slurry level control olefin; reduce short circuit circulation; spare parts wear light, low maintenance and repair costs; simple structure, easy maintenance; low energy consumption; good air dispersion; low chemical consumption, saving investment and so on.

Selection of spodumene flotation reagents

At present, the  beneficiation methods of spodumene  mainly include: manual separation, thermal disintegration, magnetic separation, resuspension method,  flotation method  and combined beneficiation method. Among them, the flotation method of spodumene is the most studied in the laboratory and the most widely used mineral processing method in industry. 1. Cationic collectors The cationic collectors used in the flotation of spodumene ore are mainly amine collectors, which flotate gangue minerals such as quartz, feldspar and mica under acidic conditions, and leave the spodumene at the bottom of the tank. This method is often used in the roughing of spodumene, and cannot directly obtain spodumene concentrate with higher purity, and needs to be used in conjunction with other sorting methods. In production practice, Yan Gengsheng used  the process of flotation of spodumene  with mixed soap and diesel oil under alkaline conditions after flotation of mica with phylloylamine under acidic cond

How to use inclined plate thickener for tailings dry discharge

 Tailings treatment is an important part of mine production. Concentration in dry tailings discharge is an important link in achieving dry stacking. It not only directly affects the processing capacity of filter equipment, but also affects the resistance of filter cakes. The particle is resistive to the filter cake, so according to the characteristics of iron tailings, there is a new type of thickener . The flow of tailings slurry in the thickener is ideally slow. As soon as the solid particles leave the flow layer, they will be considered as sediment. This model is also called shallow sedimentation. The sedimentation occurs in the void between the inclined plates. Within the cavity, but due to the small spacing between the inclined plates, it creates favorable conditions for the formation of laminar flow. The clarified overflow water moves upward along the inclined plate space, and the solid particles settle between the two plates, and only need to settle to a small distance to fall o

A new type of coarse particle flotation machine for rough grinding and flotation in mines

By -
 Coarse ore flotation has always been one of the key technologies for mine coarse grinding and flotation to reduce energy consumption. An iron ore plant in Anhui Province has a very small content of mica in the iron ore of the first grinding product. Recovery value. However, there are generally two ways to recover mica at present: one is coarse-grained regrind and reselection; the other is to choose equipment suitable for coarse-grained mineral flotation. However, during the inspection of the production site, it was found that many of the mica minerals in the second-stage grinding products in this iron ore did not meet the particle size requirements of flotation, and the density of mica was small, and most of them showed flaky structure. The overflow of the cyclone ran out, causing the inspection and screening operation to be blocked first, so regrinding is not suitable for the recovery of coarse mica.     The design principle of coarse-grained flotation machine is that coarse-grained
