Gravity concentration of Wolframite with uneven thickness

Gravity concentration of Wolframite with uneven thickness

Wolframite is an important tungsten ore, which is widely used in industrial production. However, Wolframite with uneven thickness will have a certain impact on the extraction of tungsten, so gravity concentration is required. This paper will introduce the gravity concentration operation steps of Wolframite with uneven thickness.

I. Significance of Wolframite gravity concentration

Wolframite is a kind of tungsten ore, which mainly contains tungsten, iron, copper, lead, zinc and other elements. Among them, tungsten is an important metal material widely used in the manufacturing of tungsten wires, alloys, and other fields. However, the tungsten content in Wolframite is not high, so gravity separation is needed to improve the extraction rate of tungsten and the grade of tungsten.

2、 Principle of Wolframite gravity concentration

The principle of Wolframite gravity separation is to separate according to the difference of physical and chemical properties of various minerals in the ore. In Wolframite, tungsten minerals mainly include Wolframite, Scheelite, scheelite, etc. Their density, magnetic, electrical and other physical properties are different, so they can be separated by gravity separation, magnetic separation, electrical separation and other methods.

3、 Operation steps of Wolframite gravity concentration

1. Crushing: crush Wolframite to a certain size. Generally speaking, the particle size of Wolframite should be less than 0.5mm.

2. Preparation before beneficiation: Wolframite is washed and screened to remove impurities, mud and other substances.

3. Gravity separation: put Wolframite into gravity concentrator for separation. Gravity concentrator is a device that uses the density difference of minerals to separate minerals through different gravity fields. In gravity separation of Wolframite, flotation method or sedimentation method is generally used for separation.

4. Magnetic separation: magnetic separation of Wolframite after gravity separation. Magnetic separation is a device that uses the magnetic differences of minerals for separation, separating minerals through a magnetic field. In the magnetic separation of Wolframite, high-strength magnetic separators are generally used for separation.

5. Electric separation: the Wolframite after magnetic separation is electrically separated. Electric separation is a device that uses the electrical differences of minerals for sorting, and separates minerals through an electric field. In the electrical separation of Wolframite, the high-voltage electrostatic separator is generally used for separation.

4、 Precautions for Wolframite gravity concentration

1. Before gravity concentration of Wolframite, sufficient preparation shall be made to remove impurities, mud and other substances.

2. In the process of Wolframite gravity separation, appropriate separation methods should be selected according to the ore properties and process requirements.

3. In the process of Wolframite gravity concentration, attention should be paid to the maintenance of equipment to ensure its normal operation.

4. In the process of Wolframite gravity concentration, attention should be paid to environmental protection and safety to avoid harm to the environment and personnel.

5、 Conclusion

The gravity concentration of Wolframite with uneven thickness is a Committed step to improve the extraction rate of tungsten and the grade of tungsten. By using methods such as gravity separation, magnetic separation, and electrical separation, the extraction rate and grade of tungsten can be effectively improved. In the process of Wolframite gravity concentration, attention should be paid to the maintenance and repair of equipment to ensure the normal operation of equipment. At the same time, attention should be paid to environmental protection and safety to avoid harm to the environment and personnel.
