How to select tungsten from tungsten tailings

Tungsten is an important metallic element widely used in fields such as metallurgy, electronics, chemical engineering, aerospace, etc. However, the mining and utilization of tungsten resources has always been a challenge. Tungsten tailings contain a large amount of tungsten resources, and how to select tungsten from them has become one of the research hotspots. This article will introduce how to select tungsten from tungsten tailings, hoping to be helpful to readers.

1、 Characteristics of tungsten tailings

Tungsten tailings refer to the waste generated after processing tungsten ore through processes such as beneficiation and flotation. The main components of tungsten ore tailings are quartz, Calcite, Wollastonite, etc., which contain rich tungsten resources, but the tungsten ore tailings are small in size and uneven in Granularity, so it is difficult to directly beneficiate.

II. Tungsten ore tailings selection method

1. Reselection method

The gravity separation method is to perform gravity separation on the tailings of tungsten ore, separating impurities such as tungsten ore and quartz through gravity separation. The advantages of gravity separation method are simple operation, low equipment investment, but low beneficiation efficiency, and inability to completely separate tungsten ore and impurities.

2. Flotation method

The flotation method involves the flotation of tungsten ore tailings, utilizing the different surface properties of impurities such as tungsten ore and quartz to separate them in a gas or liquid medium. The advantage of flotation method is high beneficiation efficiency, which can completely separate tungsten ore and impurities. However, the equipment investment is large, the operation is complex, and the technical requirements for operators are high.

3. Magnetic separation method

Magnetic separation method utilizes the magnetic differences between impurities such as tungsten ore and quartz for separation, and separates impurities such as tungsten ore and quartz through the action of a magnetic field. The advantages of magnetic separation method are low equipment investment and simple operation, but the beneficiation efficiency is low and cannot completely separate tungsten ore and impurities.

3、 Issues to be noted during tungsten selection process

1. Pre treatment of tungsten tailings

The Granularity of tungsten ore tailings is uneven, so pretreatment such as crushing and screening is required for subsequent beneficiation.

2. Equipment selection

Different tungsten selection methods require different equipment, and suitable equipment needs to be selected based on the actual situation.

3. Proficiency in operating techniques

During the tungsten selection process, it is necessary to master certain operating techniques and be proficient in the operation of equipment to avoid affecting the beneficiation efficiency and equipment lifespan.

4、 Conclusion

Tungsten tailings contain abundant tungsten resources, and tungsten selection is an important task. This article introduces three methods for tungsten separation, namely gravity separation, flotation, and magnetic separation. During the tungsten selection process, attention should be paid to the pre-treatment of tungsten tailings, equipment selection, and proficiency in operating techniques. I hope this article can be helpful to readers and help them better understand how to select tungsten from tungsten tailings.
