Tungsten ore sorting method

Tungsten ore is an important metal ore. Its main component is tungsten, which is a high-strength, high-density, and high melting point metal. The mining and sorting of tungsten ore is crucial for the development of the tungsten industry. In the process of tungsten ore sorting, the sorting method is a very crucial step. This article will introduce some commonly used methods for tungsten ore separation.

1、 Reselection method

The gravity separation method is a commonly used method for tungsten ore separation. Its principle is to separate tungsten ore according to the density difference between tungsten ore and other minerals. In the process of gravity separation, the tungsten ore needs to be crushed and ground first, and then separated by a gravity separator. Gravity sorting machines can be divided into flotation machines, centrifuges, sloshing machines, etc. These equipment can separate tungsten ore according to the density difference between tungsten ore and other minerals, so as to realize the separation of tungsten ore.

II. Flotation method

Flotation method is another commonly used method for tungsten ore separation. Its principle is to separate tungsten ore from other minerals by utilizing the differences in surface properties. In the flotation process, it is first necessary to crush and grind the tungsten ore, and then immerse it in a reagent solution. Through the action of the reagent, the surface properties of the tungsten ore and other minerals are changed, thereby achieving the separation of the tungsten ore and other minerals. Flotation method can be divided into air flotation, oil flotation, foam flotation, etc. These devices can separate tungsten ore based on the differences in surface properties between tungsten ore and other minerals, thereby achieving the separation of tungsten ore.

3、 Magnetic separation method

The magnetic separation method is a tungsten ore separation method that utilizes magnetic differences for separation. In the magnetic separation process, the tungsten ore needs to be crushed and ground first, and then separated through a magnetic separator. Magnetic separators can be divided into wet magnetic separators and dry magnetic separators. In a wet magnetic separator, tungsten ore is separated from other minerals by the action of water. In a dry magnetic separator, tungsten ore is separated from other minerals through the action of airflow. Magnetic separation method can separate tungsten ore based on the magnetic differences between tungsten ore and other minerals, thus achieving the separation of tungsten ore.

IV. Electric separation method

Electric separation method is a tungsten ore separation method that utilizes electrical differences for separation. In the process of electric separation, the tungsten ore needs to be crushed and ground first, and then separated through an electric separator. Electric separator can be divided into electrostatic separator and high-voltage separator. In an electrostatic separator, tungsten ore is separated from other minerals through the action of static electricity. In a high-voltage electric separator, tungsten ore is separated from other minerals through the action of a high-voltage electric field. The electric separation method can separate tungsten ore based on the difference in electrical properties between tungsten ore and other minerals, thereby achieving the separation of tungsten ore.

5、 Comprehensive selection method

Comprehensive sorting method is a tungsten ore sorting method that combines multiple sorting methods. In the comprehensive sorting process, different sorting methods can be selected for comprehensive use based on the differences in the properties of tungsten ore and other minerals. For example, the gravity separation method can be used for preliminary separation, followed by flotation, magnetic separation, electrical separation, and other methods for further separation. The comprehensive sorting method can improve the sorting efficiency of tungsten ore, thereby improving the recovery rate of tungsten ore.

Conclusion

The tungsten ore sorting method is a very important link in the process of tungsten ore mining and sorting. The commonly used tungsten ore separation methods include gravity separation, flotation, magnetic separation, electrical separation, and comprehensive separation. In actual production, different sorting methods can be selected for comprehensive use based on the differences in properties between tungsten ore and other minerals, thereby improving the sorting efficiency and recovery rate of tungsten ore.
