As an important metal mineral resource, nickel is widely used in all walks of life. In terms of nickel ore beneficiation methods, flotation is often used as the main operation plan. During the beneficiation process, different chemicals are added to cooperate with the flotation machine. After flotation is completed, what are the common flotation equipment in nickel ore concentrators? Let’s introduce it below.

At present, there are three main types of flotation equipment commonly used in nickel ore beneficiation plants (based on different mixing methods and aeration methods), respectively. It is a mechanical stirring, aerated stirring, gas separation flotation machine.

1. Mechanical agitator flotation machine for nickel ore

When the mechanical agitator flotation machine is running, it mainly uses the high-speed rotation of the impeller of the flotation machine to make the cylinder A certain negative pressure is generated inside, and then the external air is sucked in by a thin straw with a slurry suction function. Under the cutting of the slurry by the negative pressure, bubbles of a certain size are generated and dispersed in the slurry. Through the action of chemicals, useful (or gangue) minerals are made available. On the bubbles, it floats to the flotation surface and is scraped out by the scraper to complete the flotation operation.

This type of flotation machine has the functions of self-priming and self-priming. The flotation machine has a simple structure and does not require additional configuration (such as a blower or a lifting pump) in the application. The medium ore foam can return by itself. , but the impeller speed of this type of flotation machine is large, the energy consumption is high, and the wear of the flow parts is serious, and the flow parts are replaced more frequently. In addition, since it has its own suction function and is not provided by a row of external configurations, the suction volume is small.

2. Inflatable stirred flotation machine for nickel ores

Inflatable agitated flotation machine When working, the slurry is stirred through the impeller, and air is supplied from the outside of the blower. It does not have the function of self-priming and self-priming. The medium ore returns need The lifting pump completes the feeding of the mine. Therefore, the flotation machine has a large aeration capacity, small wear of flow parts, and low energy consumption.

However, since it does not have the ability to self-prime slurry, the configuration of each operation room of the flotation machine needs to adopt a ladder configuration. Not only the infrastructure cost is high, but also the equipment quantity of the lifting pump is high. Considering all things considered, the flotation machine needs to adopt a ladder configuration. Due to the large number of external configurations, the overall power consumption of machine selection is relatively large.

3. Gas separation flotation machine in Nickel Mine

The gas separation flotation machine is used The pressure reduction method causes the gas in the slurry to precipitate and form bubbles to complete the flotation operation. This type of flotation machine has small bubble size, good dispersion, large aeration volume, fast flotation speed, and small footprint.

The above is an introduction to the characteristics of the three major flotation machine types. In actual production, which type of flotation machine to choose needs to be determined based on the ore properties of the mineral, process requirements, processing plant conditions, etc. For the suitable type of flotation machine, do not choose the equipment based on a single property. It is recommended to choose a flotation machine manufacturer with good quality to purchase equipment.

The above is an introduction to the flotation machine equipment available for several nickel ores mainly produced by Xinhai Mining. Xinhai not only has many types of flotation machines, We can also provide beneficiation test services and customized nickel ore beneficiation plan services based on nickel ore beneficiation needs, which can effectively extend the service life of the flotation machine. , Improve nickel ore flotation indicators.
