Black tungsten beneficiation process flow

Wolframite is an important tungsten ore, whose main components are Tungstate and iron minerals. The technological process of wolframite beneficiation is the process of separating Wolframite from raw ore. In this process, a series of physical and chemical methods need to be used to achieve separation. This article will introduce the process flow and operating steps of wolframite beneficiation.

1、 Black tungsten beneficiation process flow

The process flow of wolframite beneficiation mainly includes steps such as crushing, grinding, flotation, gravity separation, selection, and tailings treatment. Below, we will introduce the specific operating procedures of these steps separately.

1. Crushing

Wolframite needs to be crushed after mining. The purpose of crushing is to break the raw ore into appropriate sizes for subsequent grinding processing. Crushing equipment usually uses jaw crushers and cone crushers.

2. Grinding

Grinding is the process of finely grinding the crushed raw ore. Grinding equipment usually uses ball mills and flotation machines. During the grinding process, an appropriate amount of reagent needs to be added to improve the flotation effect.

3. Flotation

Flotation is the process of separating wolframite after grinding. Flotation usually uses air flotation and oil flotation methods. In the flotation process, it is necessary to add an appropriate amount of reagent to adjust the pH value and Surface charge of the pulp, so as to improve the flotation effect.

4. Reselection

Gravity separation is to further separate the wolframite after flotation. The heavy medium selection method and centrifugal selection method are usually used for re selection. In the process of gravity separation, appropriate heavy medium or centrifuge shall be selected according to the density difference of wolframite to achieve the purpose of separation.

5. Selection

Cleaning is a process of fine separation of wolframite after gravity separation. Selection usually uses gravity and magnetic separation methods. In the cleaning process, appropriate equipment shall be selected according to the density and magnetic difference of wolframite to achieve the purpose of separation.

6. Tailings treatment

Tailings treatment is the process of treating the tailings generated during the beneficiation process. Tailings treatment usually adopts methods such as drying, leaching, and landfill. During the tailings treatment process, environmental protection measures need to be taken to protect the environment.

2、 Operation steps of wolframite beneficiation process flow

1. Crushing operation steps

(3) Control the grinding time and grinding particle size to achieve the best flotation effect.

3. Flotation operation steps

(1) Check the equipment to ensure its normal operation.

(2) Put the wolframite after grinding into the flotation machine, and add appropriate reagents.

(3) Adjust the pH value and Surface charge of pulp to improve flotation effect.

4. Steps for reselection operation

(1) Check the equipment to ensure its normal operation.

(2) Put the wolframite ore after flotation into the gravity separation equipment, and add an appropriate amount of heavy medium.

(3) According to the density difference of wolframite, select appropriate heavy medium or centrifuge to achieve the purpose of separation.

5. Selected operation steps

(1) Check the equipment to ensure its normal operation.

(2) Put the wolframite after gravity separation into the cleaning equipment, and select appropriate equipment according to the density and magnetic difference of wolframite.

(3) Control the selection time and particle size to achieve the best separation effect.

6. Operation steps for tailings treatment

(1) Dry the generated tailings to reduce moisture content.

(2) Leaching the dried tailings to recover useful metals.

(3) Landfill the tailings that have not been recovered to reduce their impact on the environment.

3、 Summary

The process of wolframite beneficiation is a complex task that requires a series of physical and chemical methods to achieve separation. In the process of wolframite beneficiation, each step is very important and the quality of each operation step needs to be strictly controlled. At the same time, environmental protection measures need to be taken to protect the environment. Through the introduction of this article, I believe everyone has a deeper understanding of the wolframite beneficiation process flow.
