Tungsten sand tailings gravity separation process flow

Tungsten sand is an important metal mineral widely used in aviation, aerospace, military, electronics, chemical and other fields. However, during the mining process of tungsten sand, a large amount of tungsten tailings are generated, which contain a large amount of tungsten minerals. However, the treatment of tungsten tailings has always been a challenge. In order to effectively treat tungsten tailings and extract useful minerals from them, we need to use the tungsten tailings gravity separation process.

1. Properties of Tungsten Sand Tailings

Tungsten sand tailings are mainly composed of quartz, tungsten minerals, sulfide, Pyrite and other minerals, of which tungsten minerals are relatively high. The main component of tungsten mineral is Tungstate, and its chemical formula is H2WO4. The specific gravity of tungsten minerals is relatively large, generally between 6 and 7.

2、 Treatment process of tungsten sand tailings

The treatment process of tungsten tailings mainly includes four stages: rough selection, intermediate selection, selection, and tail selection.

1. Rough selection stage

The rough selection stage is the first step in the treatment of tungsten tailings. At this stage, we need to perform preliminary screening and washing of tungsten tailings to separate the particles containing tungsten minerals. Generally, heavy medium separation and cyclone separation methods are used for rough selection.

2. Selection stage

The intermediate stage is the second step in the treatment of tungsten tailings. At this stage, we need to further improve the grade of tungsten minerals. Generally, flotation method is used for intermediate selection, which floats particles containing tungsten minerals and then undergoes defoaming and dehydration treatment.

3. Selection stage

The selection stage is the third step in the treatment of tungsten tailings. At this stage, we need to further improve the grade of tungsten minerals to meet industrial requirements. Generally, gravity and flotation methods are used for selection to separate particles containing tungsten minerals.

4. Final selection stage

The tail selection stage is the final step in the treatment of tungsten tailings. At this stage, we need to treat the tailings and further extract the tungsten minerals from them. Generally, magnetic separation and gravity separation methods are used for tailings separation to separate particles containing tungsten minerals.

3、 Advantages of tungsten tailings gravity separation process flow

The tungsten tailings gravity separation process has the following advantages:

1. The grade of tungsten minerals has been improved, meeting industrial requirements.

2. Reduced the discharge of tungsten sand tailings and reduced its impact on the environment.

3. Improved the recovery rate of tungsten minerals and reduced production costs.

4、 Conclusion

The tungsten tailings gravity separation process is an effective method for treating tungsten tailings. Through the four stages of rough selection, intermediate selection, selection, and tail selection, tungsten minerals in tungsten tailings can be effectively extracted, meeting industrial requirements. The tungsten tailings gravity separation process has the advantages of high efficiency, environmental protection, and economy, making it a worthwhile method for promoting tungsten mineral treatment.
