Overview of tungsten ore selection process

Tungsten ore is an important non-metallic mineral resource widely used in aviation, aerospace, electronics, metallurgy, chemical and other fields. The mining and processing of tungsten ore is a complex process that requires a series of process flows for selection. This article will introduce an overview of tungsten ore beneficiation technology, including mining, ore crushing, ore grinding, gravity separation, flotation, tailings treatment, and other links.

1、 Mining

There are two main methods of mining tungsten mines: open-pit mining and underground mining. Open pit mining is generally suitable for situations where the ore body is large and the depth of the deposit is shallow. Blasting, loading, and other methods are used for mining. Underground mining is suitable for situations where the ore body is small and the deposit is deeply buried, using methods such as tunnels and shafts for mining.

2、 Ore crushing

The tungsten ore after mining needs to be crushed for subsequent beneficiation processes. Ore crushing generally includes various methods such as jaw crusher, cone crusher, and impact crusher. The jaw crusher is a commonly used crushing equipment with the advantages of simple structure, convenient operation, and high crushing efficiency.

3、 Ore grinding

Ore grinding refers to refining the broken tungsten ore to facilitate subsequent beneficiation processes. Ore grinding is generally carried out using equipment such as ball mills and ore mills. The ball mill is a commonly used grinding equipment with advantages such as high grinding efficiency and low energy consumption.

4、 Reselection

Gravity separation refers to the physical separation of tungsten ore after grinding, separating minerals of different densities. Re selection is generally carried out using methods such as heavy medium selection and centrifugal selection. Among them, heavy medium sorting is a commonly used sorting method, which has the advantages of good sorting effect and simple operation.

V. Flotation

Flotation refers to the chemical separation of tungsten ore after gravity separation, which floats out useful minerals. Flotation is generally carried out using methods such as reagent flotation and air flotation. Among them, reagent flotation is a commonly used flotation method, which has the advantages of good separation effect and simple operation.

6、 Tailings treatment

Tailings treatment refers to the waste treatment of tungsten ore after flotation. Tailings treatment is generally carried out through methods such as concentration and filtration. Concentration is a commonly used tailings treatment method, which has the advantages of low waste content and good treatment effect.

summary

The tungsten ore beneficiation process is a complex process that requires a series of process flows for beneficiation. This article introduces an overview of tungsten ore beneficiation technology, including mining, ore crushing, ore grinding, gravity separation, flotation, tailings treatment, and other links. I hope this article can provide some reference for everyone and help them better understand the tungsten ore selection process.
