Tungsten sand tailings gravity separation technology

Tungsten sand tailings gravity separation technology

Tungsten sand is an important metal ore widely used in aviation, military, electronics, chemical and other fields. However, the mining and processing process of tungsten sand generates a large amount of tailings, which contain a large amount of tungsten ore and other impurities. If not treated, it not only wastes resources but also causes environmental pollution. Therefore, the gravity separation technology of tungsten tailings is particularly important.

Characteristics of tungsten sand tailings

Tungsten sand tailings are characterized by high hardness, high density and fine Granularity. The tungsten ores in tailings are mainly Wolframite and Scheelite. The tungsten content of Wolframite is up to more than 60%, but it also contains more impurities. The tungsten content of Scheelite is low, but it contains less impurities.

2、 Treatment Method of Tungsten Sand Tailings

1. Reselection method

The gravity separation method is currently one of the main methods for treating tungsten tailings. This method utilizes the differences in physical properties between tungsten ore and impurities to separate tungsten ore from tailings through gravity separation, flotation, and other methods. The advantages of gravity separation method are simple operation, short process flow, but high equipment requirements, and low recovery rate of tungsten ore.

2. Flotation method

Flotation method is a method of separating tungsten ore from impurities through physical and chemical methods. This method mainly utilizes the different affinity between tungsten ore and water, and separates tungsten ore from tailings by adjusting the properties of water and adding chemicals. The advantages of flotation method are high recovery rate and short process flow, but there are high requirements for the selection and regulation of reagents.

3. Magnetic separation method

Magnetic separation method is a method of separating tungsten ore and impurities based on their magnetic differences. This method mainly separates tungsten ore from tailings by adjusting the magnetic field strength and selecting magnetic materials. The advantages of magnetic separation method are simple operation and high recovery rate, but it requires high equipment requirements and is only suitable for magnetic materials.

3、 Development trend of tungsten tailings gravity separation technology

With the continuous development of technology, tungsten tailings gravity separation technology is also constantly innovating and improving. In the future, the development trend of tungsten tailings gravity separation technology will mainly focus on the following aspects:

1. Joint application of multiple technologies

At present, the treatment methods for tungsten tailings mainly include gravity separation, flotation, and magnetic separation, but each of these methods has its own advantages and disadvantages. In the future, the treatment method of tungsten tailings will adopt a combination of multiple technologies to improve recovery rate and treatment efficiency.

2. Application of environmentally friendly technologies

The treatment process of tungsten tailings will generate a large amount of wastewater and waste residue, causing certain environmental pollution. In the future, tungsten tailings gravity separation technology will adopt more environmentally friendly technologies and materials to reduce its impact on the environment.

3. Application of Automation Technology

The treatment process of tungsten tailings requires multiple steps of operation, which requires high technical requirements for operators. In the future, the tungsten tailings gravity separation technology will adopt automation technology to reduce the technical requirements and labor intensity for operators.

4、 Conclusion

The tungsten tailings gravity separation technology is an important technology, which is of great significance for improving the recovery rate of tungsten ore and reducing its impact on the environment. In the future, with the continuous development of technology, tungsten tailings gravity separation technology will continue to innovate and improve to meet the growing market demand.
