Beneficiation process of tungsten tin ore

Beneficiation process of tungsten tin ore

Tungsten tin ore is an important metal ore widely used in aerospace, military, electronics and other fields. However, the beneficiation process of tungsten tin ore is relatively complex and requires special processes for treatment. In this article, we will introduce the basic principles and operational steps of the tungsten tin ore beneficiation process to help readers better understand this process.

1、 The beneficiation principle of tungsten tin ore

The beneficiation principle of tungsten tin ore is to separate the ore through physical and chemical methods to extract useful components such as tungsten and tin. Specifically, the beneficiation process of tungsten tin ore includes the following steps:

1. Crushing: Crush the original ore to make it reach the Granularity suitable for beneficiation.

2. Grinding: Refine the crushed ore for better separation.

3. Classification: Classify the milled ore by screening and other methods to make it reach the Granularity range suitable for beneficiation.

4. Gravity separation: A gravity separation machine is used to separate useful components such as tungsten and tin from the ore.

5. Flotation: Flotation is carried out using a flotation machine to separate impurities from the ore and ensure that it meets the purity requirements.

2、 Operation steps of tungsten tin ore beneficiation process

1. Crushing: Crushing the original ore, usually using a jaw crusher or impact crusher for crushing. The Granularity of crushed ore is generally below 10mm.

2. Grinding: The crushed ore is finely ground, usually using a ball or rod mill for grinding. The Granularity of the ground ore is generally below 0.074mm.

3. Grading: The finely ground ore is classified, usually using methods such as screening or cyclone classification. The Granularity of ore after classification is generally 0.074mm-0.038mm.

4. Gravity separation: The graded ore is subjected to gravity separation, usually using a gravity separator for gravity separation. The gravity separator separates the ore according to the density difference of the ore, and the separated useful components such as tungsten and tin are generally high in content.

5. Flotation: Flotation is carried out on the re selected ore, usually using a flotation machine for flotation. The flotation machine separates the ore based on the difference in specific gravity, and the impurities separated are generally low in content to meet the purity requirements.

3、 Notes on the beneficiation process of tungsten tin ore

1. The Granularity of ore is strictly required, and too fine or too coarse will affect the beneficiation effect.

2. The selection of gravity concentrators and flotation machines should be based on the properties and requirements of the ore, and different selection options will affect the beneficiation effect.

During the beneficiation process, attention should be paid to environmental protection and the discharge of wastewater, exhaust gas, and waste residue should be minimized as much as possible.

4、 Conclusion

The beneficiation process of tungsten tin ore is a complex process that requires the use of special processes for treatment. This article introduces the basic principles and operational steps of tungsten tin ore beneficiation, hoping to help readers better understand this process. When beneficiating tungsten tin ores, attention should be paid to the Granularity, type selection and environmental protection of ores to ensure the beneficiation effect and production safety.
