Tungsten tin ore gravity separation method

Tungsten tin ore gravity separation method

Tungsten tin ore is an important metal ore, which contains metal elements such as tungsten and tin, which are widely used in modern industrial production. However, there are many difficulties in the mining and beneficiation process of tungsten tin ore, the most important of which is how to re concentrate tungsten tin ore to improve its grade and recovery rate. This article will introduce some common tungsten tin ore gravity separation methods to help readers better understand and master knowledge in this field.

1、 Re-selection process flow

The gravity separation process of tungsten tin ore generally includes three stages: rough selection, intermediate selection, and selection. Among them, rough selection mainly involves preliminary separation of ores through mechanical and hydraulic forces, removing impurities and waste rocks from them. Intermediate separation involves further separation of ore through methods such as gravity beneficiation, flotation, and magnetic separation, in order to improve its grade and recovery rate. And selection is to finely separate the ore that has been selected, achieving the final beneficiation effect.

2、 Gravity beneficiation method

The gravity beneficiation method is a common method of tungsten tin ore gravity separation, which utilizes the different settling velocities of minerals with different densities in the ore under the action of gravity for separation. Generally speaking, tungsten minerals in tungsten tin ore have a higher density than tin minerals, so they can be separated by gravity beneficiation. Gravity beneficiation mainly includes methods such as heavy medium beneficiation, centrifugal beneficiation, and vibration beneficiation.

3、 Flotation method

Flotation method is a common method of tungsten tin ore gravity separation, which utilizes the differences in physical and chemical properties of mineral surfaces to selectively separate minerals through bubble adsorption and separation. In the flotation process of tungsten tin ore, a mixture of tin oxide and tungsten sulfide is generally used as a flotation agent. The flotation method mainly includes direct flotation, reverse flotation, and complex flotation methods.

4、 Magnetic separation method

Magnetic separation method is a common method of tungsten tin ore gravity separation, which utilizes the different magnetic properties of minerals under the action of a magnetic field for separation. In the magnetic separation process of tungsten tin ore, high-strength magnetic separators are generally used for selective separation of minerals. Magnetic separation mainly includes dry magnetic separation and wet magnetic separation methods.

5、 Electroselection method

Electric separation method is a common method of tungsten tin ore gravity separation, which utilizes the different conductivity and electrochemical properties of minerals under the action of an electric field for separation. In the electrical separation process of tungsten tin ore, a high-voltage electric field is generally used for selective separation of minerals. The electrical separation method mainly includes direct electrical separation, reverse electrical separation, and composite electrical separation methods.

6、 Conclusion

Overall, the tungsten tin ore gravity separation method has a variety of options, each with its applicable occasions and advantages and disadvantages. Therefore, in actual industrial production, appropriate gravity separation methods should be selected based on the characteristics of the ore and the requirements of beneficiation, in order to improve beneficiation efficiency and economic benefits.
