Flotation Machine Product features

Maintaining recovery and ensuring availability and sustainability while keeping costs under control is challenging.

System advantages

The slurry surface is equipped with an automatic control device for easy adjustment.
The mineralization system, distribution system, and unmanned fully automatic control system are adopted, which are easy to operate and the product is guaranteed.

Material advantages

The flotation machine adopts special wear-resistant materials, which is light and reliable, and the equipment has a long service life.


There are no moving parts in the tank body, which is easy to maintain and repair.

Processing capacity

Large processing capacity, high sorting accuracy, and high production efficiency.
Low energy consumption and low operating cost.

Performance advantages

The implementation of segmented operation ensures a good flotation environment.


The process flow is diversified. For coal quality selection, the roughing process or the fine selection process can be selected according to the actual situation, which makes the operation more flexible.

Working principle

What Is The Working Principle Of The Flotation Machine

1. Reagent mixing: In the flotation machine, a certain amount of reagent is first added to adjust the pulp to a certain pH and reagent concentration. The active substances in the reagent react with the surface of the ore to form a bubble adsorption layer.

2. Bubble adsorption: Through the rotation of a mechanical stirring device (such as an impeller), the pulp forms a vortex flow in the flotation machine. The air in the pulp is sucked in by the impeller and fully mixed with the pulp between the impeller blades. After the reagent is mixed with the pulp, the active substances in the reagent react with the surface of the ore to form a bubble adsorption layer. These bubbles form a bubble group in the pulp, and the bubble surface carries ore particles adsorbed by the reagent.

3. Slurry stirring: The stirring device pushes the impeller or propeller in the flotation machine to make the pulp and bubbles mix more evenly. This step ensures that the ore particles adsorbed by the bubbles are fully mixed with the pulp, improving the mineral processing effect.

4. Ore sedimentation: After bubble adsorption and stirring, the ore particles in the pulp are divided into two parts: flotation foam and sedimentation tailings. The ore particles in the flotation foam have a lower density and will float to the surface of the flotation machine tank to form a foam layer, which is a useful mineral. The ore particles in the sedimentation tailings have a higher density and will sink to the bottom of the flotation machine tank. This part is usually excluded as tailings.

5. Separation and collection: By adjusting the tank depth and feed amount of the flotation machine, the sedimentation speed and flotation effect of the ore can be controlled. The foam layer that floats to the surface is discharged from the flotation machine through a scraper or gravity flow, which is the selected concentrate. The tailings at the bottom are discharged through the tailings discharge port.

6. Circulation treatment: The flotation machine is usually designed as a circulation treatment system, and part of the slurry and foam can be returned for reprocessing to improve the efficiency of mineral processing and the quality of the concentrate.
