Tungsten ore selection technology

Tungsten ore is an important metal ore widely used in aviation, aerospace, electronics, chemical and other fields. However, the extraction and beneficiation of tungsten ore has always been a challenge. In this article, we will introduce a new type of tungsten ore separation technology to help you better extract and beneficiate tungsten ore.

1、 Disadvantages of traditional tungsten ore selection technology

Traditional tungsten ore processing techniques mainly include heavy medium beneficiation, flotation, magnetic separation, and other methods. Although these methods can extract tungsten ore to a certain extent, they have the following drawbacks:

1. Low beneficiation efficiency: Traditional beneficiation methods are difficult to remove some impurities in tungsten ore, resulting in low beneficiation efficiency.

2. High energy consumption: Traditional mineral processing methods require a large amount of energy input, resulting in energy waste.

3. Environmental protection issues: Traditional mineral processing methods generate a large amount of wastewater and waste residue, causing pollution to the environment.

2、 Advantages of New Tungsten Ore Selection Technology

In order to solve the problems of traditional tungsten ore selection technology, scientists have proposed a new type of tungsten ore selection technology. This technology mainly includes steps such as oxidation roasting, acid leaching, and ion exchange. Compared to traditional tungsten ore selection technology, the new technology has the following advantages:

1. High beneficiation efficiency: New technologies can effectively remove impurities in tungsten ore and improve beneficiation efficiency.

2. Low energy consumption: New technologies require less energy input, reducing energy waste.

3. Environmental protection issues have been addressed: New technologies can reduce the generation of wastewater and waste residue, and the pollution caused to the environment has also been addressed.

3、 Operation steps of a new tungsten ore selection technology

1. Oxidative roasting: the tungsten ore is oxidized and roasted to convert it into Sodium tungstate.

2. Acid leaching: dissolve Sodium tungstate in acid solution to obtain soluble tungstic acid.

3. Ion exchange: Tungstic acid is separated and enriched through ion exchange resin.

4. Desorption: the enriched tungstic acid is desorbed through the desorption agent to obtain pure Sodium tungstate.

5. Reduction: Sodium tungstate is reduced to obtain pure tungsten powder.

IV. Conclusion

The new tungsten ore processing technology can effectively improve beneficiation efficiency, reduce energy waste, and solve environmental issues. I believe that with the continuous progress of technology, the new tungsten ore separation technology will be more widely applied.
