Separation method of Wolframite

Separation method of Wolframite

Wolframite is an important tungsten ore with high hardness, high melting point, high density and other characteristics, which is widely used in aviation, aerospace, military and other fields. In the process of mining and utilization of Wolframite, beneficiation is a very important step. This paper will introduce the methods and steps of Wolframite separation.

1、 Beneficiation method of Wolframite

1. Reselection method

Gravity concentration is one of the main methods for Wolframite separation. This method uses the different characteristics of Wolframite and other minerals in the gravity field to separate Wolframite from other minerals through gravity separation. The specific operation steps are as follows:

(1) Mix Wolframite with other minerals to make pulp.

(2) The slurry is put into the gravity separator, and Wolframite is separated from other minerals by the action of gravity field.

(3) According to the density difference between Wolframite and other minerals, adjust the parameters of gravity field to achieve the best separation effect.

2. Flotation method

Flotation is another common method for Wolframite separation. This method uses the different characteristics of Wolframite and other minerals in water to separate Wolframite from other minerals by flotation separation. The specific operation steps are as follows:

(1) Mix Wolframite with other minerals to make pulp.

(2) Put the pulp into the flotation cell, add flotation agent and bubbles to separate Wolframite from other minerals.

(3) According to the buoyancy difference between Wolframite and other minerals under the action of flotation agent and bubbles, adjust the parameters of flotation cell to achieve the best separation effect.

2、 Beneficiation steps of Wolframite

1. Preparation of raw materials

The first step of Wolframite beneficiation is raw material preparation. Before the separation of Wolframite, the raw materials need to be crushed, ground, etc., in order to better conduct the separation.

2. Gravity or flotation

Gravity concentration method or flotation method can be selected for Wolframite separation. Gravity concentration method is applicable to the case where the density difference between Wolframite and other minerals is large, while flotation method is applicable to the case where the density difference between Wolframite and other minerals is small.

3. Selection

After the separation of Wolframite, it needs to be cleaned. Cleaning refers to the further treatment of Wolframite to remove impurities and other minerals and improve the purity and quality of Wolframite.

4. Drying

After the cleaning of Wolframite, the Wolframite needs to be dried. Drying refers to evaporation of water from Wolframite for better processing and utilization.

3、 Conclusion

Wolframite dressing is a very important step in the process of Wolframite mining and utilization. Gravity concentration method or flotation method can be selected for Wolframite separation. No matter which method is used, the steps of raw material preparation, separation, cleaning and drying are required to achieve the best separation effect and the highest utilization value of Wolframite.
