Nickel, as an important metal mineral resource, is widely used in all walks of life. In the nickel ore beneficiation method, flotation method is often used as the main beneficiation method. In the beneficiation process, different reagents will be added to complete flotation with flotation machines. What types of nickel ore flotation cell are there? How to choose? Let's introduce it.
At present, there are three main types of nickel ore flotation equipment (according to the difference between the stirring method and the aeration method), namely, mechanical stirring, aeration stirring, and gas separation flotation cell.
When the mechanical stirring flotation cell is running, it mainly uses the high-speed rotation of the impeller of the flotation cell to generate a certain negative pressure inside its cylinder, and then the external air is sucked in by the fine suction pipe with the suction function, and a certain size of bubbles are generated under the cutting of the negative pressure of the pulp to disperse in the pulp, and the useful (or gangue) minerals are adsorbed on the bubbles through the action of the agent, and then float up to the flotation surface, which is scraped out by the scraper, Complete the flotation operation.
This type of flotation cell has the functions of self suction and self suction of pulp. The flotation cell is simple in structure and does not need additional configuration (such as blower or lifting pump) in application. The foam of Zhongkuang can flow back automatically. However, this type of flotation cell has large impeller speed, high energy consumption, severe wear of flow passage parts, and frequent replacement of flow parts. In addition, due to its own suction function, not a row of external configuration, the suction volume is small.
When the aerated stirring flotation cell works, it stirs the pulp through the impeller, and the air is fed from the outside of the blower. It does not have the function of self-priming and self-priming. The return of middling ore requires the lifting pump to complete the ore feeding. Therefore, the flotation cell has large aeration capacity, small wear of overflow parts and low energy consumption.
However, due to the lack of self-priming capacity, the configuration of each operation room of the flotation cell needs to adopt ladder configuration, which not only has high capital construction cost, but also has a high number of lifting pumps. In comprehensive consideration, the flotation cell has a large overall power consumption due to its many external configurations.
The gas separation flotation cell uses the depressurization method to make the gas in the pulp separate out and form bubbles to complete the flotation operation. This type of flotation cell has small bubble size, good dispersion, large air volume, fast flotation speed and small floor area.
The above is the introduction of the characteristics of the three types of flotation cells. In actual production, which type of flotation cell to choose depends on the ore properties of minerals, process requirements, concentrator conditions, etc. to determine the appropriate type of flotation cell. Do not select equipment based on a single property. It is recommended to select a flotation cell manufacturer with good quality to purchase equipment.
The above is an introduction to the flotation cells and equipment available for several nickel ores produced by Xinhai Mineral Equipment. Xinhai not only has many types of flotation cells, but also can provide beneficiation test services and customized nickel ore beneficiation scheme services according to the needs of nickel ore beneficiation, which can effectively improve the service life of flotation cells and improve the nickel ore flotation index.
