Beneficiation process of Wolframite

Beneficiation process of Wolframite

Wolframite is an important tungsten ore, which is widely used in industrial production. However, the beneficiation process of Wolframite is a very complicated problem. This article will introduce the beneficiation process of Wolframite to help readers understand the beneficiation process of Wolframite.

1、 Overview of Wolframite

Wolframite is a Sulfide mineral, mainly composed of Tungsten disulfide. The color of Wolframite is black with metallic luster. Wolframite is one of the main tungsten ores and an important non-metallic mineral.

II. Beneficiation process of Wolframite

The beneficiation process of Wolframite includes grinding, flotation, gravity concentration, desulfurization and other links. Beneficiation process of Wolframite will be introduced in detail below.

1. Grinding

Grinding is the first step of Wolframite beneficiation, and its purpose is to grind Wolframite ore into suitable particle size. The grinding equipment includes ball mills, rectangular mills, etc. The particle size of grinding is generally 0.074mm.

2. Flotation

Flotation is an important part of Wolframite beneficiation. The flotation of Wolframite generally uses Sodium oxide and Sodium acetate as regulators, naphthyl oxalic acid as collector, and petroleum alkane as foam agent. In the flotation process, Wolframite and foam rise to the liquid level together to form foam pulp, which is then separated by concentrator.

3. Reselection

Gravity concentration is the further processing of Wolframite after flotation. The equipment for re selection includes re selection machines, centrifuges, etc. The purpose of gravity concentration is to further improve the grade and recovery of Wolframite.

4. Desulfurization

Desulfurization is the last step of Wolframite beneficiation. During the flotation of Wolframite, Sodium sulfide will be added to the pulp to inhibit the flotation of Wolframite. Therefore, desulfurization treatment is required. The methods of desulfurization include oxidation, reduction, etc.

3、 Problems in Wolframite beneficiation process

There are some problems in the beneficiation process of Wolframite. First of all, the processing technology of Wolframite is complex, which requires a lot of energy and costs. Secondly, the flotation of Wolframite is difficult, and efficient flotation agents and collectors are needed. Finally, the beneficiation process of Wolframite will produce a large amount of wastewater and waste residue, which will pollute the environment.

4、 Conclusion

Wolframite is an important tungsten ore, which is widely used in industrial production. The beneficiation process of Wolframite includes many links such as grinding, flotation, gravity separation, desulfurization, etc. There are some problems in the beneficiation process of Wolframite, which need further research and improvement.
