The flotation machine, a full-name flotation concentrator, works based on the difference in contact and adhesion between mineral particles and bubbles in the flotation tank. In the flotation machine, the slurry treated with reagents is stirred and aerated, so that some of the mineral particles are selectively fixed on the bubbles, float to the surface of the slurry, and are scraped out to form foam products, while the rest are retained in the slurry to achieve the purpose of separating minerals.
Types and structures of flotation machines for mineral processing
There are many structural forms of flotation machines, and the most commonly used is the mechanical stirring flotation machine. According to the type of mechanical stirring device, flotation machines can be divided into different models, such as XJ type, XJQ type, GF type, SF type, rod type, etc. In addition, there are different types such as aerated stirring flotation machines and aerated flotation machines. The aerated stirring flotation machine is equipped with a mechanical stirring device and uses an external fan to force air in; while the aerated flotation machine has no mechanical agitator, and the air for aeration is provided by a specially set air compressor.
The working process of the flotation machine mainly includes the following steps:
• Crushing and grinding: The raw ore is crushed and ground to make it suitable for flotation.
• Adjusting reagents: Adding reagents such as regulators and collectors to the flotation tank to adjust the chemical properties of the slurry to improve the flotation performance of useful minerals.
• Stirring and feeding: The stirring device fully mixes the slurry and air and feeds it into the flotation tank.
• Bubble generation: Bubbles are generated in the slurry by providing compressed air or other gases to the flotation tank.
• Mineral adhesion: Useful mineral particles come into contact with bubbles and adhere to the surface of the bubbles, floating to the top of the flotation tank.
• Settling waste rock: Due to its strong adhesion, the waste rock particles cannot combine with the bubbles and sink to the bottom of the flotation tank.
• Collecting useful minerals: The floating useful mineral particles form scum, which is collected by the scum tank or other collection devices.
• Discharge of waste rock: After the waste rock settles to the bottom of the flotation tank, it is discharged through the mud discharge device or the waste rock tank.
Advantages and applications of mineral processing flotation machines
Mineral processing flotation machines have significant advantages in mineral processing technology, such as high-efficiency separation, multi-stage separation, and combined processes. It can not only improve mineral processing efficiency, but also contribute to environmental protection, such as reducing the use of chemical agents, wastewater treatment, and comprehensive resource utilization. Therefore, flotation machines play an indispensable role in modern mineral processing technology.
