Bauxite iron removal equipment

Detailed explanation of iron removal methods in bauxite 1. Physical method The physical method is to remove iron from bauxite by using the difference in physical properties. Common physical methods include gravity separation, magnetic separation and flotation.


1. Gravity separation: Utilize the difference in density of different minerals to carry out mineral separation through equipment such as shaking tables and chutes. The density of iron minerals in bauxite is relatively large, and some iron minerals can be removed by gravity separation.


2. Magnetic separation: Utilize the strong magnetic characteristics of iron minerals, and magnetic separation can effectively remove iron minerals. Magnetite is common in bauxite, and magnetic separation can be used to separate them from bauxite.

3. Flotation: Utilize the difference in surface properties of different minerals, adjust the surface properties through flotation agents, and separate bauxite from iron minerals. In the flotation process, commonly used agents include collectors, inhibitors and activators.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device.  The trommel screen  is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
