The beneficiation plant process of tungsten ore

Tungsten ore is an important metal ore with extensive applications in industrial production. The beneficiation process of tungsten ore refers to the process of extracting tungsten from the original tungsten ore through a series of physical and chemical treatments. This article will introduce the beneficiation process of tungsten ore, including steps such as ore crushing, grinding, flotation, and selection.

1、 Ore crushing

Tungsten ore is usually mined underground and needs to be crushed first after being transported to a beneficiation plant. Ore crushing refers to the process of coarse crushing, intermediate crushing and fine crushing of the original tungsten ore through the crusher and other equipment to make it meet certain Granularity requirements. The broken tungsten ore is usually particles with a diameter of less than 10mm, providing a foundation for subsequent processes such as grinding and flotation.

2、 Ore grinding

ore grinding refers to the fine grinding of broken tungsten ore through a grinding machine to achieve a certain fineness requirement. Grinding is an important step in the mineral processing process, with the aim of refining the mineral particles in the ore and improving flotation efficiency. Grinding machines usually use equipment such as ball mills and rod mills. During the grinding process, an appropriate amount of water and chemicals need to be added to achieve the best grinding effect.

3、 Ore flotation

Ore flotation refers to the flotation of tungsten ore after grinding through a flotation machine, separating the tungsten minerals from other impurities. Flotation is the core link in the mineral processing process, and its principle is to achieve the separation of minerals by changing the hydrophilicity or hydrophobicity of mineral particles and flotation agents through physical or chemical methods. The flotation of tungsten ore usually adopts dehydration sedimentation flotation method or iron oxide mineral flotation method, and the specific flotation process needs to be selected based on the properties of the ore and the actual situation of the beneficiation plant.

4、 Ore selection

Ore selection refers to the process of selecting tungsten ore after flotation treatment through a selection machine, and further purifying the tungsten minerals in it. Selection machines usually use equipment such as gravity separators and centrifuges, and their principle is to separate mineral particles according to their density, size, and other characteristics through physical actions such as gravity and centrifugal force. During the selection process, multiple selections are required to achieve the best separation effect.

V. Conclusion

The beneficiation process of tungsten ore is a complex process that requires multiple steps to ultimately extract high-purity tungsten. This paper introduces the Committed step of tungsten ore crushing, grinding, flotation and concentration. These steps need to strictly control various parameters to ensure the stability and efficiency of the beneficiation process. In future industrial production, the application prospects of tungsten ore will become increasingly broad, and the continuous innovation of beneficiation technology will also bring new opportunities and challenges to the extraction and utilization of tungsten ore.
