Beneficiation technology of Wolframite

Wolframite is an important tungsten ore, tungsten is an important metal element, widely used in aerospace, military, electronics and other fields. The beneficiation technology of Wolframite is very important to the development and utilization of tungsten resources. This paper will introduce the beneficiation technology of Wolframite, including the nature of Wolframite, beneficiation flowsheet, beneficiation equipment and problems needing attention in the beneficiation process.

1、 Properties of Wolframite

Wolframite is a kind of quartz vein type tungsten ore, which is mainly composed of Tungstate minerals, such as Scheelite, Wolframite and scheelite. The color of Wolframite is black, the hardness is 5.5-6.5, and the specific gravity is 6.0-7.5. The mineral composition of Wolframite is complex, which contains many valuable metal elements, such as copper, lead, zinc, silver, etc. The beneficiation of Wolframite is mainly aimed at the tungsten element in it.

II. Beneficiation process of Wolframite

The beneficiation process of Wolframite includes ore crushing, grinding, flotation and other steps.

1. Ore crushing

The ore of Wolframite is generally hard and needs to be crushed. Commonly used crushing equipment includes jaw crushers, cone crushers, etc. After ore crushing, it is generally necessary to screen and separate the coarse and fine ore for subsequent grinding and flotation.

2. Grinding

Grinding is the process of finely grinding the ore for subsequent flotation. Commonly used grinding equipment includes ball mills, rod mills, etc. During the grinding process, it is necessary to control the grinding time and grinding fineness to ensure the flotation effect.

3. Flotation

Flotation is the process of suspending minerals and flotation agents in water and separating them through physical and chemical interactions. The flotation of Wolframite generally adopts multi-stage flotation process, including rough separation, scavenging, concentration and other steps. Commonly used flotation agents include xanthate solution, black potion solution, etc. During the flotation process, it is necessary to control the type and dosage of flotation agents to ensure the effectiveness of flotation.

3、 Beneficiation equipment of Wolframite

The beneficiation equipment of Wolframite includes crushing equipment, grinding equipment, flotation equipment, etc. Commonly used equipment includes jaw crushers, cone crushers, ball mills, rod mills, flotation machines, etc. The selection of beneficiation equipment should be determined based on the properties of the ore and the beneficiation process.

4、 Matters to be noted during the beneficiation process

In the beneficiation process of Wolframite, the following problems should be paid attention to:

1. The selection and crushing of ore should be reasonable to ensure subsequent grinding and flotation effects.

2. Grinding time and grinding fineness should be controlled to ensure the flotation effect.

3. The type and dosage of flotation agents should be properly controlled to ensure the effectiveness of flotation.

The selection of beneficiation equipment should be determined based on the properties of the ore and the beneficiation process.

During the beneficiation process, attention should be paid to environmental issues and the discharge of wastewater and waste residue should be minimized as much as possible.

5、 Summary

The beneficiation technology of Wolframite is the key to the development and utilization of tungsten resources. This paper introduces the properties of Wolframite, beneficiation flowsheet, beneficiation equipment and problems needing attention in beneficiation process. I hope it will be helpful to the mineral processing workers of Wolframite.
