Flotation is one of the effective methods for treating bauxite. By adding flotation reagent, it combines with minerals and gives After inflating, it is stirred to generate fine foam, which effectively separates hydrophobic or hydrophilic minerals. In bauxite operations, the target mineral for flotation is diaspore, and the selected chemicals are often fatty acid collectors, which can effectively capture diaspore.

There are many equipment that can be used for flotation of bauxite, such as mechanical agitation flotation machines, inflatable agitation flotation machines, etc., all of which can be used. So how to choose a suitable flotation machine equipment? Woolen cloth? In view of the characteristics of my country's bauxite with high aluminum, high silicon, low iron and low aluminum to silicon ratio, the flotation machine selected for bauxite flotation operation must meet the following requirements:

1. Flotation The aeration volume of the flotation machine must be subject to any conditions

Generally, during bauxite flotation, the aeration volume of the flotation machine needs to be about 0.1~0.3 m3/(m2·min);

2. The stirring force in the flotation machine tank should be moderate

Usually, the stirring force of the flotation machine is too strong, which will affect the mineralization of bubbles, and the stirring force, which is too weak, will affect the dispersion of slurry and bubbles. Therefore,the stirring force of the flotation machine used for bauxite flotation should not be too strong or too weak, but should be moderate;

3. The slurry page of the flotation machine should be stable

Because of the bauxite The particle size of mineral flotation particles is relatively fine, and the unstable separation zone slurry will cause the adsorbed mineral particles to fall off and affect the mineral processing index. Therefore, when selecting a flotation machine, you should choose to ensure the stability of the flotation separation zone;

4. Fluid dynamics should meet the requirements

A large amount of foam will be produced during bauxite flotation, especially the slurry will also contain a large amount of microbubbles. Therefore, a flotation machine is required. The fluid dynamics generated in the tank can meet the flotation dynamics requirements of a large number of fine bubbles in the flotation machine;

5. The flotation machine must have strong slurry suction capacity

Bauxite The flotation foam is small and has high viscosity. The foam in the foam tank is not easy to break. Moreover, the amount of foam is large, the process circulation is large, and the foam transportation is difficult. Therefore, a flotation machine with sufficient slurry suction capacity must be used to make the process smooth;

The above are some requirements that flotation machines for bauxite mines need to meet. In addition, the optional flotation machine can also have automation functions. When used, it should be able to ensure that the liquid level control system has high The accuracy ensures that the liquid level in the flotation machine is within a reasonable range.
