Tungsten ore beneficiation process

Tungsten ore beneficiation process is a technology used to extract tungsten from tungsten ore. Tungsten is an important metal with high melting point, density, and hardness, and is widely used in aviation, aerospace, military, electronics, and other fields. This article will introduce the basic principle, process flow, and operational steps of tungsten ore beneficiation.

Basic Principles of Tungsten Mineral Processing

Tungsten ore usually contains more non-metallic minerals such as quartz, Calcite and Wollastonite, and a small amount of tungsten minerals such as Wolframite and Scheelite. The basic principle of tungsten ore beneficiation is to separate tungsten containing minerals from non-metallic minerals based on their physical and chemical properties. The main beneficiation methods include gravity separation, flotation, magnetic separation, electric separation, etc.

2、 Process flow of tungsten ore beneficiation

The process flow of tungsten ore beneficiation usually includes steps such as crushing, grinding, gravity separation, flotation, desliming, and selection.

1. Crushing

First, the raw ore is crushed by the crushing equipment to reach the Granularity suitable for further processing. Commonly used crushing equipment includes jaw crushers, cone crushers, etc.

2. Grinding

The crushed ore is finely ground by grinding equipment to improve beneficiation efficiency. Commonly used grinding equipment includes ball mills, ore mills, etc.

3. Reselection

After grinding, the ore is sent to the gravity separation equipment for gravity separation, separating tungsten containing minerals from non-metallic minerals. The commonly used gravity separation equipment includes gravity concentrators, centrifugal concentrators, etc.

4. Flotation

The tungsten containing minerals after re selection are subjected to flotation equipment to separate them from flotation reagents. Commonly used flotation equipment includes air flotation machines, mechanical flotation machines, etc.

5. Desliming

The tungsten containing minerals after flotation still contain a certain amount of impurities such as sediment, which requires desliming treatment. Commonly used desliming equipment includes desliming cyclones, desliming screens, etc.

6. Selection

After desliming, tungsten containing minerals are sent to the selection equipment for selection, in order to achieve higher tungsten grades. Commonly used selection equipment includes vibration concentrators, centrifugal concentrators, etc.

3、 Operating steps for tungsten ore beneficiation

1. Select appropriate beneficiation processes and equipment based on the properties of the ore and the requirements of the beneficiation process.

2. Conduct pre-treatment work such as crushing and grinding of the raw ore.

3. Feed the pre processed ore into the beneficiation equipment for beneficiation.

4. Conduct post-processing work such as desliming and selection of tungsten containing minerals after beneficiation.

5. Treat the waste generated during the beneficiation process to meet environmental requirements.

4、 Conclusion

The tungsten ore beneficiation process is an important technology that can extract tungsten, an important metal, from tungsten ore. The basic principle of tungsten ore beneficiation is to separate tungsten containing minerals from non-metallic minerals based on their physical and chemical properties. The process flow of tungsten ore beneficiation includes steps such as crushing, grinding, gravity separation, flotation, desliming, and selection. When conducting tungsten ore beneficiation operations, it is necessary to select appropriate beneficiation processes and equipment based on the properties of the ore and the requirements of the beneficiation process, in order to achieve higher beneficiation results.
