How to gravity concentrate wolframite powder

Wolframite is an important tungsten ore, which contains high concentration of tungsten and other useful metals. The wolframite powder is obtained through a series of processes such as grinding, flotation and magnetic separation. However, in the production process, the grade of wolframite powder is not high enough, and gravity separation is required. This paper will introduce the gravity separation process and operation steps of wolframite powder.

I. Significance of gravity separation of wolframite powder

Wolframite powder is an important tungsten ore powder, which is widely used to manufacture alloys, electrodes, high-temperature materials, etc. However, in the production process, the grade of wolframite powder is not high enough, and gravity separation is needed. Gravity concentration can improve the grade of wolframite powder, reduce production costs and improve economic benefits.

2、 Gravity separation process of wolframite powder

The gravity separation process of wolframite powder mainly includes heavy medium separation, heavy liquid separation, flotation, etc. Among them, heavy liquid separation is the most commonly used process in the gravity separation of wolframite powder.

Heavy liquid separation is a physical beneficiation method that uses suspensions of different densities to separate mixtures containing minerals of different densities. The heavy liquid separation process of wolframite powder is as follows:

1. Grinding: grinding wolframite into wolframite powder of certain size.

2. Heavy medium separation: the wolframite powder is preliminarily separated through the heavy medium separator, and a part of wolframite powder with high grade is separated.

3. Heavy liquid separation: the wolframite powder after preliminary separation is further separated through the heavy liquid separator. In the process of heavy liquid separation, wolframite powder is put into suspension with different densities, and the density difference of suspension is used to separate wolframite powder. After heavy liquid separation, wolframite powder with high grade can be obtained.

4. Magnetic separation: the wolframite powder after heavy liquid separation is subject to magnetic separation through a magnetic separator to remove the magnetic minerals in it and obtain wolframite powder with higher grade.

3、 Operation steps of wolframite powder gravity separation

1. Grinding: grinding wolframite into wolframite powder of certain size. When grinding, attention should be paid to controlling the grinding time and the amount of grinding medium used to avoid excessive grinding and contamination of the grinding medium.

2. Dense medium separation: the wolframite powder is preliminarily separated through the dense medium separator. When selecting heavy media, attention should be paid to adjusting the parameters of the heavy media separator to achieve better sorting results.

3. Heavy liquid separation: the wolframite powder after preliminary separation is further separated through the heavy liquid separator. When selecting heavy liquids, attention should be paid to adjusting the density and flow rate of the suspension to achieve better separation results.

4. Magnetic separation: the wolframite powder after heavy liquid separation is magnetic separated through a magnetic separator. During magnetic separation, attention should be paid to adjusting the magnetic field strength and parameters of the magnetic separator to remove magnetic minerals from it.

5. Grade determination: determine the grade of wolframite powder after gravity separation to determine whether the grade meets the requirements.

Summary

The gravity separation of wolframite powder is an important process to improve the grade of wolframite powder, reduce production costs and improve economic benefits. Heavy liquid separation is the most commonly used process in the gravity separation of wolframite powder. Its operation steps include grinding, heavy medium separation, heavy liquid separation, magnetic separation and grade determination. During the operation process, attention should be paid to adjusting various parameters to achieve better sorting results.
